Whether you’re considering laser hair removal, battling hair thinning, or simply curious about why your hair grows the way it does—understanding the hair growth cycle is key to making informed decisions about your hair and scalp care.
At RxRejuvenate, we believe that education is the foundation of effective treatment. Here’s a closer look at the natural hair growth cycle and how it impacts everything from shedding to regrowth and treatment timing.
The 4 Stages of Hair Growth
Hair doesn’t grow continuously—it moves through a cyclical process of growth, rest, and shedding. Each strand on your body is at a different stage of this cycle at any given time.
1. Anagen (Growth Phase)
This is the active growth phase when hair follicles produce new strands. It lasts anywhere from 2–7 years depending on genetics, and about 85-90% of your hair is in this phase at any moment.
Why it matters: Treatments like laser hair removal are most effective during this phase.
2. Catagen (Transition Phase)
A short, 2–3 week phase where hair growth slows, and the follicle begins to shrink. Only about 1–2% of hairs are in this phase.
Why it matters: Hair detaches from the blood supply, prepping to enter the resting phase.
3. Telogen (Resting Phase)
Lasting around 2–3 months, hair is no longer growing but has not yet fallen out. About 10–15% of your hairs are in this phase at any time.
Why it matters: Stress or illness can push more hair into this phase, leading to shedding.
4. Exogen (Shedding Phase)
This is when the old hair falls out and makes room for new growth. Shedding 50–100 hairs a day is normal during this phase.
Why it matters: Shedding is part of the cycle—but excessive shedding may need attention.
