What is DHT?
DHT is a derivative of testosterone that binds to hair follicle receptors, causing them to shrink and eventually stop producing hair. This process results in male pattern baldness, also known as androgenetic alopecia, and can affect both men and women. DHT-blocking shampoos aim to prevent hair loss by reducing DHT levels in the scalp, thus promoting hair growth and maintaining hair density.

It's essential to follow up with a conditioner to maintain hair health. Be cautious when using shampoos containing preservatives, parabens, sulfates, or other potentially irritating ingredients.

Hair loss can result from various factors, including age, stress, hormones, illness, infections, and medications. Seek advice from a medical professional if you're concerned about hair loss, especially if it's sudden, patchy, or involves body hair, as this may indicate an underlying medical condition requiring diagnosis and treatment.
Also, consult a doctor if you have other symptoms along with hair loss, such as itching, burning, or pain, or if hair loss affects your quality of life.
