Scleroderma can cause hair loss, and the pattern depends on which form of the disease you have. In localized scleroderma affecting the scalp, fibrotic tissue directly replaces hair follicles and can leave permanent bald patches. In systemic scleroderma, widespread vascular damage and skin tightening lead to more diffuse thinning. On top of the disease itself, some of the medications used to treat scleroderma can trigger hair shedding as a side effect. The encouraging news is that treatment options exist for each of these scenarios, and research over the past decade has changed the assumption that scleroderma-related hair loss is always irreversible.
How Scleroderma Damages Hair Follicles
Scleroderma is fundamentally a disease of excess collagen. The immune system drives inflammation that eventually leads to fibrosis, the buildup of thick, hardened connective tissue in the skin and sometimes internal organs. When this process reaches the scalp, dense collagen bundles in the deeper layers of skin compress and distort hair follicles. The follicles shrink, produce thinner hairs, and in advanced cases stop producing hair altogether. A comparative trichoscopy study found that white patches located between normally arranged follicular units are a visible sign of this fibrosis and the microcirculation problems that accompany it in systemic sclerosis.1Dermatology. Trichoscopic Signs in Dermatomyositis, Systemic Lupus Erythematosus, and Systemic Sclerosis: A Comparative Study of 150 Patients
Vascular damage is the other major player. Scleroderma attacks small blood vessels throughout the body, narrowing them and reducing blood flow. Hair follicles are metabolically demanding structures that rely on a rich blood supply. When tiny scalp vessels become damaged or blocked, the follicles they feed are starved of oxygen and nutrients. This vascular insufficiency shows up clearly under magnification: trichoscopy of the frontal scalp in people with systemic sclerosis reveals abnormal vessel patterns in a majority of patients, including spider-shaped vessels in over three-quarters of cases and avascular areas (zones with virtually no visible blood supply) in about a third.2PubMed Central.

Localized Scleroderma and En Coup de Sabre
The most visually dramatic hair loss from scleroderma comes from a localized form called morphea, specifically a subtype known as en coup de sabre. The name is French for “struck by a sword” because it creates a linear band of hardened, often indented skin that runs along the forehead and up into the scalp, looking as though someone drew a line across the head. Along that band, hair follicles are destroyed by fibrosis, leaving a stripe of scarring alopecia. Traditionally, dermatologists considered this hair loss permanent because the scarring seemed to obliterate the follicular structures beyond recovery.3PubMed. Reversible alopecia in En Coup de Sabre morphea
That assumption has been challenged by case reports showing that aggressive early treatment can sometimes reverse the hair loss, even in en coup de sabre. The key seems to be intervening before fibrosis has fully replaced the follicle. Once the disease has been active for years and the scalp tissue is deeply scarred, regrowth becomes much less likely. This is one reason dermatologists emphasize early recognition and referral when a child or adult develops a linear band of hardened skin on the scalp.
Systemic Scleroderma and Diffuse Thinning
Systemic sclerosis affects the whole body, and its impact on hair tends to be more widespread but subtler than the localized forms. Rather than a dramatic bald patch, you might notice your hair becoming generally thinner, especially near the front of the scalp. The thickened, taut skin characteristic of systemic sclerosis makes it harder for follicles to cycle normally, and the vascular compromise described earlier means the scalp receives less blood flow overall.
A comparative study examining scalp changes in systemic sclerosis, lupus, and dermatomyositis found that systemic sclerosis has its own recognizable set of scalp findings. Thick collagen bundles in the skin compromise follicular architecture, leading to reduced hair shaft diameter and diffuse hair loss.1Dermatology. Trichoscopic Signs in Dermatomyositis, Systemic Lupus Erythematosus, and Systemic Sclerosis: A Comparative Study of 150 Patients Because the thinning happens gradually and diffusely, some people attribute it to aging or stress before realizing it is connected to their scleroderma. If you have systemic sclerosis and notice increased shedding, bring it up with your rheumatologist rather than dismissing it.
The Scleroderma–Alopecia Areata Connection
Scleroderma can also be linked to a completely separate hair loss condition called alopecia areata, which causes patchy, round bald spots driven by immune cells attacking healthy hair follicles. A large population-based study comparing over 51,000 people with alopecia areata to a similar number of controls found that the prevalence of systemic sclerosis was significantly higher in the alopecia areata group, with more than double the odds of having both conditions.4PubMed. The prevalence of systemic sclerosis is increased among patients with alopecia areata: a population-based study The association held even after adjusting for age, sex, ethnicity, and other health conditions.
This matters practically because the treatment approach for alopecia areata is different from the treatment for scleroderma-driven scarring alopecia. Alopecia areata is non-scarring, meaning the follicles remain alive beneath the surface and can potentially regrow hair if the immune attack is controlled. Scleroderma-related scarring alopecia, by contrast, involves physical destruction of the follicle. Getting the right diagnosis determines whether you should be treated with immunomodulators targeting the autoimmune attack on follicles or with therapies aimed at halting fibrosis. Some people with scleroderma may have both processes happening simultaneously, which makes a thorough scalp evaluation essential.
When Medications Are the Culprit
Here is an irony that catches people off guard: some of the drugs prescribed for scleroderma can themselves cause hair loss. Immunosuppressive agents used to manage scleroderma are among the medications known to trigger drug-related hair shedding.5PubMed. Hair disorders associated with autoimmune connective tissue diseases Methotrexate, one of the most commonly prescribed treatments for localized scleroderma, is a well-known cause of telogen effluvium, a form of diffuse shedding that happens when a large number of hair follicles are pushed into their resting phase simultaneously. Mycophenolate mofetil, another frequently used drug, can also thin hair in some patients.
The distinction matters because drug-induced shedding is almost always reversible once the medication is adjusted or stopped. If your hair loss worsened around the time a new drug was started or a dose increased, tell your doctor. Switching to a different agent or adjusting the dose might resolve the shedding without compromising disease control. The challenge is figuring out whether it is the disease or the treatment causing the problem, and sometimes it is both.
How Doctors Evaluate Scleroderma-Related Hair Loss
Trichoscopy, a non-invasive method of examining the scalp under high magnification, has become an increasingly valuable tool for scleroderma patients. In systemic sclerosis, trichoscopy of the frontal scalp reveals a distinctive pattern: polymorphic microvessels in roughly two-thirds of patients, spider vessels in over three-quarters, and avascular areas in about a third. In healthy individuals, these features are far less common, with spider vessels appearing in only about 6% and avascular areas in under 10%.2PubMed Central. The diagnostic value of trichoscopy in systemic sclerosis The presence of polymorphic vessels in the frontal scalp is considered characteristic enough to help confirm a systemic sclerosis diagnosis.
In localized morphea on the scalp, trichoscopy shows a different set of features: loss of follicular openings on a whitish skin surface, scattered black dots, broken hairs, twisted hairs known as pili torti, and short thick vessels at the edges of the affected area.6PubMed Central. Trichoscopic Features of Linear Morphea on the Scalp The whitish surface signals established fibrosis, while the abnormal hairs at the margins suggest active disease is still progressing outward. This distinction between the center and edges of a lesion helps doctors decide how aggressively to treat.
Trichoscopy can also help distinguish scleroderma-related hair changes from lupus or dermatomyositis, two other autoimmune diseases that affect the scalp. Each condition leaves its own recognizable fingerprint of vessel patterns and follicular changes, which means a careful scalp examination can sometimes point toward the right diagnosis before blood work comes back.1Dermatology.

Treatment Options for Scleroderma-Related Hair Loss
Treating the hair loss means treating the underlying scleroderma, and treatment choice depends on the form and severity of the disease. For localized scleroderma affecting the scalp, the standard first-line approach is methotrexate, often combined with a short course of corticosteroids to quickly dampen inflammation. The goal is to halt fibrosis before it becomes irreversible. When methotrexate does not work well enough or causes intolerable side effects, mycophenolate mofetil has shown strong results as a second-line option. In a long-term follow-up study of children with severe or methotrexate-resistant localized scleroderma, over 90% of patients treated with mycophenolate mofetil achieved inactive disease status, and all of those on methotrexate also reached that goal over a mean follow-up period of nearly a decade.7PubMed Central. Mycophenolate mofetil for methotrexate-resistant juvenile localized scleroderma An earlier study similarly found that all patients placed on mycophenolate showed clinical improvement sufficient to reduce or withdraw corticosteroids and methotrexate.8PubMed. Successful treatment of severe or methotrexate-resistant juvenile localized scleroderma with mycophenolate mofetil
For milder or more superficial scalp lesions, topical treatments can sometimes be effective. A case report of a six-year-old with en coup de sabre affecting the forehead and scalp described an excellent response to topical calcipotriene ointment, a vitamin D analog. The child experienced normalization of the sclerotic skin, hair regrowth, and improved discoloration in the affected area.9PubMed Central. En Coup de Sabre in a Pediatric Patient Treated With Calcipotriene Topical calcipotriene is much gentler than systemic immunosuppression, which makes it appealing for children and for adults with limited disease. It is not appropriate for deep or rapidly progressing lesions, but for early, shallow involvement it represents a conservative option worth discussing with your dermatologist.
Hair Transplantation After Scleroderma Stabilizes
Once scleroderma has been inactive for an extended period, surgical restoration of hair becomes a realistic option for some patients. Hair transplantation in stabilized morphea en coup de sabre has been shown to be feasible and can produce excellent cosmetic outcomes. A key innovation described in recent reports is pretreatment of the scarred recipient area with repeated sessions of autologous fat grafting (taking fat from elsewhere in the body and injecting it into the scarred scalp). This softens the fibrotic tissue, improves local blood supply, and creates a healthier environment for transplanted hair follicles to survive and integrate naturally.10PubMed Central. Successful hair transplantation following repeated lipostructure in a case of morphea en coup de sabre: a multidisciplinary and regenerative approach
This approach requires patience. The disease must be confirmed inactive, typically for at least a year or two before a surgeon will consider transplantation. The fat grafting itself may require multiple sessions spaced months apart. And there is always the risk that the disease could reactivate and damage the transplanted hair. Still, for people who have lived with a visible bald band across their forehead or scalp for years, the possibility of cosmetic restoration is significant. This is a multidisciplinary undertaking, involving a rheumatologist to confirm disease stability, a dermatologist familiar with scleroderma, and a surgeon experienced in working with scarred tissue.
Children With Scalp Scleroderma
Localized scleroderma is more common in children than systemic scleroderma, and en coup de sabre is one of the forms that preferentially affects younger patients. Hair loss on the scalp can be especially distressing for children and their families because it is visible and difficult to conceal. The good news is that children often respond well to treatment, and their capacity for tissue repair tends to be greater than that of adults.
Treatment decisions in children involve balancing the risks of immunosuppressive medications against the consequences of untreated disease. Methotrexate remains the most studied first-line systemic therapy for pediatric localized scleroderma. When children do not respond or cannot tolerate methotrexate, mycophenolate mofetil has been shown to be effective and generally well tolerated in this age group.7PubMed Central. Mycophenolate mofetil for methotrexate-resistant juvenile localized scleroderma For early or superficial lesions, topical calcipotriene offers a gentler alternative, as demonstrated in a pediatric case that achieved hair regrowth and skin normalization without systemic medication.9PubMed Central. En Coup de Sabre in a Pediatric Patient Treated With Calcipotriene The choice between these approaches depends on how deep and how rapidly the lesion is progressing.
The Emotional Weight of Visible Hair Loss
Scleroderma already takes a psychological toll through skin tightening, pain, fatigue, and limitations on daily activities. Hair loss adds another layer, particularly because it is one of the most publicly visible changes the disease can cause. Research on the mental health of people with systemic sclerosis paints a sobering picture: about 19% of patients meet criteria for a current major depressive episode, and over half have experienced one at some point in their lives.11PubMed Central. Psychiatric Symptoms and Quality of Life in Systemic Sclerosis Skin changes and alterations in physical appearance are specifically cited as contributors to psychological disturbances including anxiety and depression.
Hair loss compounds this because it can feel like a loss of identity. For women in particular, thinning hair or bald patches may be harder to accept than skin changes that can be covered with clothing. Children with en coup de sabre sometimes face questions or teasing from peers. These emotional consequences deserve direct attention from healthcare teams, not just a passing mention. If your scleroderma is causing visible hair changes and you are struggling with how it affects your self-image, bringing it up with your doctor is not vanity. It is a legitimate part of managing the disease, and there are dermatological, psychological, and cosmetic support options that can help.
Practical Steps You Can Take Now
If you have scleroderma and are noticing hair changes, a few concrete actions can make a real difference:
- Get a scalp evaluation: Ask your dermatologist about trichoscopy. The distinctive vessel patterns visible under magnification can clarify whether hair loss is from active scleroderma, medication side effects, or an overlapping condition like alopecia areata.
- Track the timeline: Note when shedding began relative to medication changes. Drug-induced hair loss often starts a few weeks to a couple of months after a new prescription or dose adjustment, which helps distinguish it from disease progression.
- Do not delay treatment: Scarring alopecia from scleroderma is much easier to prevent than to reverse. If you have a new or expanding lesion on the scalp, early systemic treatment gives the best chance of preserving hair follicles.
- Be gentle with your scalp: Tight hairstyles, excessive heat, and harsh chemical treatments can worsen hair loss in skin that is already compromised. This is not the primary cause, but minimizing mechanical stress helps protect vulnerable follicles.
- Ask about restoration options: If your disease has been stable for an extended period and you have areas of permanent hair loss, inquire about fat grafting and hair transplantation with a surgeon experienced in scleroderma patients.
Many people with scleroderma assume that hair loss is an inevitable and untreatable part of the disease. That was the prevailing view not long ago, and it still shows up in some older patient resources. The evidence now tells a more nuanced story: early treatment can prevent scarring, drug-related shedding is typically reversible, alopecia areata can be managed separately, and even established bald areas from en coup de sabre can be restored in selected cases. The single most important factor is recognizing what type of hair loss you are dealing with, because the answer shapes everything that follows.
