Laser Hair Regrowth or Low-Level Laser Therapy (LLLT) is a non-surgical therapy involving exposure of low-power laser light to the scalp to stimulate hair growth. This cold laser stimulates metabolism in the cell and blood flow to the scalp without damaging the tissues. It is mainly prescribed in Androgenetic Alopecia or pattern hair loss in both genders. It also works in resolving diffuse hair loss and reducing hair density. Telogen Effluvium, or temporary or excessive hair shedding, can be treated with LLLT to revert the hair growth cycle to normal. It can also be used as a secondary treatment, providing faster healing of the surgery and the survival of transplanted hair. The primary action is the induction of new hair growth in the inactive follicles. It makes the existing hair thicker and fuller as well. LLT reduces hair loss by extending the growth phase of the hair. Besides, it enhances the general scalp condition by boosting nutrient-rich blood circulation.
