3. Nutritional Deficiencies and Hairstyling Practices
Lack of essential nutrients like iron and zinc, along with damaging hairstyling practices, can lead to hair loss.

Blood tests may be done to check for hormonal imbalances, thyroid issues, or nutritional deficiencies that could contribute to hair loss.

A pull test can help assess hair shedding, while a scalp biopsy may be needed to examine hair follicles if scarring alopecia is suspected.
Treatments for Hair Thinning

b. Finasteride: This oral medication is typically prescribed for men. It blocks the conversion of testosterone to dihydrotestosterone (DHT), preventing hair follicle shrinkage.

PRP therapy involves injecting platelets derived from the patient’s own blood into the scalp, which can promote hair growth and has shown satisfactory results for some individuals.
