How fast does hair grow back?

Before we answer that question, let us first understand the growth pattern of your hair.

Phases of hair growth

Your hairs grow from follicles in the skin. Each follicle is a living organ inside us. Everyone was born with about 5 million hair follicles and cannot develop more later. But the growth pattern of hair do change as we age.

At any given time, your hairs grow through four phases. They are:

  • anagen, the growing phase (90% follicles)
  • catagen, the regressing phase (10-14% follicles)
  • telogen, the resting phase (1-2% follicles)
  • exogen, the shedding phase (independent from other phases)

All your hairs cycle through these phases as they grow. But the length of cycle varies by area. For example, the eyebrows complete a cycle in 4 months. Whereas, your scalp hairs take 3-4 years to cycle. A chemical signal called "epidermal growth factor" controls the hair growth cycle. In other words, the shorter the cycle, the quicker your hairs grow back.

Lasers remove hair by targeting and damaging its root under the skin. Because of that, laser treatment can only remove hairs during their growing phase. Moreover, you need to take many spaced apart laser sessions before you begin to see some results.
