The quick answer is, on average, hair growth is about ¼ inch to ½ inch a month, according to Bridgette HillsA certified, trichologist and founder Analysis of Root Cause Scalp. Of course, this can vary from person to person, but if the hair (and scalp) is healthy, hair should and will grow every month.
To better understand hair growth, professional hair stylist, Sophia porter divided into 4 main phases: Anagen, catagen, telogen and exogen. Anagen is the stage of growth, “where your hair grows and the maximum length is determined,” Porter said. This time can last from 2 to 7 years, depending on the location of each person and is the longest stage in the hair growth process. This is followed by catagen or the regressive and transitional phase. During this period of about 7 to 10 days, hair growth slows and hair follicles shrink.
According to Porter, 10-15% of the hair on the scalp is going through the telogen phase at a time. In this growth program, old hair is resting and new hair is growing. And finally, exogen is when the hair falls out of the hair follicle. “On average, a person loses between 50 and 150 hairs per day,” says Porter. So don’t panic if you see a few strands of hair in the comb.
Don’t worry if this seems overwhelming to understand. The most important thing to keep in mind is that hair growth, like everything in life, is a process and, in fact, you should see if your hair and body growth is healthy. no (see more in this section below).
