Frequently Asked Questions

How fast does hair grow?

On average about half an inch (1.25 cm) a month, or roughly 6 inches a year. Genetics, age, health and diet all affect it.

Do trims make hair grow faster?

No. Trims do not change growth from the scalp, but removing split ends prevents breakage so you keep more length.

How long does it take to grow hair to mid-back?

Starting from shoulder length, it usually takes about 1.5 to 2 years with occasional light trims.
