Natural herbal blend for hair loss & thinning hair†

Combats hair loss and thinning hair with a nutritional approach — a natural herbal blend that blocks the production of DHT and supports hair regrowth from the inside-out. The benefit is stronger, thicker, healthier hair.†
 
Research indicates that one of the primary causes of hair loss and thinning hair is due to increased level of DHT (dihydrotestosterone), the "bad" form of the hormone, testosterone. As men and women age, DHT builds up in the scalp and damages the hair-producing follicles. This eventually destroys the hair follicles which results in hair loss. NuHair® DHT Blocker combats hair loss and thinning hair with a nutritional approach — a natural supplement that nourishes and supports hair regrowth from the inside out. The benefit is thicker, fuller, healthier hair for men and women.†

Healthy hair growth consists of three phases:

1. Anagen phase:
This is the growth phase of the hair cycle during which new hair is formed; lasting from two to six years in a healthy person. Some people have difficulty growing their hair beyond a certain length because they have a short anagen phase of hair growth, whereas people who easily grow long hair have a long anagen phase of hair growth.
2. Catagen phase:
This is the transitional stage between the growing (anagen) and resting (telogen) phases of the hair's growth cycle, lasting about one to three weeks. During this phase, hair growth stops and the outer layer, or sheath, of the hair follicle shrinks and attaches to the root of the hair. This is the formation of what is known as a club hair, which will eventually be pushed out and replaced with new hair.
3. Telogen phase:
This is the resting phase of the hair growth cycle that lasts about 3 months. The hair does not grow in the telogen phase. While hair mostly stays attached to the follicle during this stage, natural shedding does occur in this stage. The hair follicle re-enters the anagen or growth phase at the end of the telogen phase, and the hair growth cycle continues.
