Hydrophobic hair repels water, making it difficult to get wet and moisturize. This condition is due to a tightly sealed outer layer, or cuticle, which prevents water from penetrating the hair shaft. While healthy hair has some water-repelling properties to protect it, an overly hydrophobic state prevents it from receiving necessary moisture. This tightly bound cuticle acts as a barrier, causing water and products to bead up on the surface rather than being absorbed.
Signs of Hydrophobic Hair
When washing, it may feel like it takes an unusually long time for your hair to become fully saturated with water. This resistance also means that styling products often seem to sit on top of the hair, leaving a sticky or greasy residue rather than being absorbed. This can make the hair feel heavy and stiff.
You might also notice that your hair dries much faster than you would expect. Because less moisture gets into the hair shaft, less moisture also escapes, leading to rapid drying times. A simple way to check for this is the spray bottle test: mist a section of dry, clean hair with water and observe if the water beads on the surface or is absorbed.
What Causes Hair to Repel Water?
The tendency for hair to repel water can be an inherent structural trait. Many people with hydrophobic hair have low porosity hair, a genetic condition where the cuticle layers are compact and tightly bound. This flat, closed structure naturally resists the entry of water. This is not a sign of unhealthy hair; it indicates that the protective outer layer is intact.
External factors can also contribute to or mimic the effects of low porosity hair. The accumulation of ingredients from hair products is a frequent cause, as heavy silicones, butters, and some oils can form a film that blocks moisture. Mineral deposits from hard water can also build up over time, creating a barrier that prevents products from penetrating the hair cuticle.
Care Routine for Hydrophobic Hair
Incorporate a clarifying or chelating shampoo into your washing schedule. These shampoos are formulated to remove product residue and mineral buildup, clearing the way for moisture to enter the hair shaft. Regular use, such as once a week or a couple of times a month, can prevent the accumulation that leads to water repellency.
After clarifying, apply conditioner to damp, rather than soaking wet, hair. Using gentle, indirect heat can assist in opening the tightly sealed cuticle. You can achieve this by covering your conditioned hair with a shower cap and a warm towel, or by using a hair steamer. This controlled warmth helps lift the cuticle, allowing the conditioner to penetrate more deeply.
When selecting styling products, opt for those that are lightweight and water-based. Heavy formulations containing silicones and oils should be used sparingly to avoid buildup. Applying products to damp or even dripping wet hair can aid in absorption, ensuring that as the hair dries, it seals in moisture.
