Each hair develops from a follicle — a narrow pocket in the skin — and goes through three phases of growth. Anagen (A), the active growth phase, lasts two to seven years. Catagen (), the transition phase, lasts about two weeks. During this phase, the hair shaft moves upward toward the skin's surface, and the dermal papilla (the structure that nourishes cells that give rise to hair) begins to separate from the follicle. Telogen (C), the resting phase, lasts around three months and culminates in the shedding of the hair shaft.
Viviscal is a natural hair-growth supplement that promotes hair growth in people with thinning hair. It contains a marine complex known as AminoMar C. This is made of minerals, vitamins, and shark and mollusk powder. These ingredients help to regenerate new cells and strengthen existing cells. You have to take the pills twice a day for at least six months in order to see results. Viviscal also makes a shampoo and conditioner.
