Perifollicular fibrosis is a condition in which scar tissue forms around the hair follicle. This scar tissue can interfere with the normal growth of the hair and lead to hair loss. In some cases, perifollicular fibrosis may be the result of an injury or inflammation in the hair follicle, but the exact cause is not always clear. In severe cases, perifollicular fibrosis can lead to permanent hair loss.
Treatment for perifollicular fibrosis involves advanced topical treatments, such as Spark or Roots Shampoo.
