Leire Barrutia, dermatologist and health expert: "The best thing you can do for your hair is wash it daily."

Dr. Leire Barrutia , a dermatologist and hair health specialist, has sent out a clear message: "The best thing you can do for your hair is wash it daily." Contrary to the belief that frequent washing can damage hair, the expert warns that not doing so encourages the accumulation of oil and impurities. This disrupts the scalp's natural balance and can trigger problems such as inflammation, itching, and dandruff . According to Barrutia, proper hygiene is the foundation for maintaining healthy hair.

When washing isn't enough or goes on for days without doing so, the scalp can react negatively. Barrutia points out that this lack of cleansing alters the skin's microbiome and affects the local immune system . As a result, conditions such as seborrheic dermatitis, which manifests as visible and persistent discomfort, are common. Furthermore, there is a relationship between this inflammation and certain types of hair loss. Preventing these changes starts with a regular washing routine.

The hair follicle needs a clean and stable environment

One of the key points the dermatologist emphasizes is the concept of the hair follicle's "immune privilege." This natural protection keeps it safe from aggressive immune responses. However, in situations of sustained inflammation , such as those caused by poor hygiene, this privilege is lost. Consequently, the immune system can attack the follicle itself, which could lead to forms of alopecia. Keeping the scalp clean is, therefore, an effective preventative measure .

To avoid these types of complications, the doctor recommends washing your hair at least every other day . However, for people prone to excess oil production, it's ideal to do so daily. Far from damaging the hair, this habit helps maintain skin balance. Barrutia also suggests alternating different shampoos if you want to protect the hair fiber without sacrificing proper cleansing. " Your scalp will thank you ," the specialist concludes.
