Several hair growth therapies are available, each with varying degrees of effectiveness:
Minoxidil: This topical treatment is FDA-approved for hair growth. Histological studies show that Minoxidil prolongs the Anagen phase and enlarges miniaturized hair follicles. Finasteride: An oral medication that inhibits the conversion of testosterone to dihydrotestosterone (DHT), a hormone linked to hair loss. Histological analysis reveals that Finasteride can reduce hair follicle miniaturization. Platelet-Rich Plasma (PRP): This therapy involves injecting concentrated platelets from the patient's blood into the scalp. Histology shows that PRP promotes hair follicle regeneration and increases the Anagen phase duration. Low-Level Laser Therapy (LLLT): LLLT uses light energy to stimulate hair follicles. Histological evidence suggests that LLLT enhances cell proliferation and improves blood circulation in the scalp. Hair Transplantation: This surgical procedure involves moving hair follicles from a donor area to a bald or thinning area. Histology helps in assessing the viability and proper placement of transplanted follicles.
