What’s hair all about?

Hair has two separate parts: the follicle and the hair shaft. The follicle lies below the scalp and produces the hair shaft (strand) that you see growing out of your skin’s epidermis layer. The follicle is alive. The hair shaft is not – it’s made of fragile, dead cells that have no regenerative properties.

The follicle is a sac of skin tissue buried deep in the scalp. It has a bulb at the bottom. The sebaceous gland is attached to the follicle. It gives hair its shine by producing a natural lubricant called sebum. The follicle is where the personal characteristics of hair are decided: curly or straight, dry or oily, and thickness.

Hair has three basic layers: the medulla, the cortex, and the cuticle. The medulla is the innermost core of the hair where the body and strength is determined. The cortex is the middle (and largest) layer. It provides strength to the hair shaft, and determines the color, texture and elasticity. The cuticle protects hair from the environment by forming a tightly packed layer of protective scales that overlap.

How does hair grow?

Hair grows from the hair follicle at an average rate of one-half inch per month. Each hair grows for four to seven years, after which it enters a “resting phase,” and then falls out. A new hair begins growing in its place between three weeks and three months later. At any one time, 85 percent of hair is growing and 15 percent is resting. The life of a hair consists of three phases:
