A number of treatments are available to repair damaged hair follicles, including topical creams and lotions, anti-inflammatory medications and surgery, according to LiveScience. However, the right treatment for repairing damaged hair follicles depends upon the cause and the extent of the damage, as well as on the cost of the treatment and how far the patient wants to go with treatment.
Maureen Salamon, a health contributor for LiveScience, notes that hair loss occurs for a number of reasons such as heredity, treating the hair harshly with styling and chemical treatments, hormone imbalances, illnesses and surgery, vitamins or medications, nutritional deficits, and aging. The Cleveland Clinic claims that topical creams and lotions generally work more effectively for people who have hair loss due to heredity. However, Dr. Paradi Mirmirani, staff dermatologist at the Permanente Medical Group, stresses to WebMD that doing less to the hair works best when the damage comes from factors like heat, chemicals, dyes, or styling. Furthermore, the owner and head stylist at Spa Christine Larry Baron also emphasizes maximizing hair health before damage sets in and even cutting the hair to let it grow in a healthy way. He also warns against heating hair before putting product on it.
