What is it?
The anagen phase is the active growth stage of the hair growth cycle. During this period, cells in the hair follicles divide rapidly, causing hair to grow about half an inch per month. For scalp hair, this phase can last anywhere from two to eight years, and at any given moment, about 85-90% of your hair is in this stage. The length of the anagen phase is largely determined by genetics and dictates the maximum length your hair can achieve. Shorter hairs, like eyelashes and eyebrows, have a much shorter anagen phase.
Why is it trending?
Interest in the anagen phase is growing as consumers become more educated about the science of hair health. With concerns about hair thinning and loss on the rise, people are seeking targeted, science-backed solutions. The beauty and wellness industry has responded by developing products and treatments aimed at stimulating hair follicles and extending the anagen phase. This focus has popularized ingredients like biotin, caffeine, and minoxidil, which claim to prolong the growth period, resulting in thicker, healthier, and longer hair.
How does it affect people?
The duration of the anagen phase directly impacts hair length and volume. A long anagen phase results in longer potential hair growth, while a short phase limits it. Factors like age, stress, hormonal changes, and nutritional deficiencies can shorten this phase, leading to increased shedding and noticeable hair thinning. As people age, the anagen phase naturally shortens. Understanding this phase helps individuals make informed decisions about hair care, diet, and treatments to support healthy follicles and maintain hair density throughout their lives.
