Bleached body hair typically lasts between two to four weeks.
While bleaching effectively lightens existing hair, the results are not permanent. The primary reason for this is the natural hair growth cycle. New hair continually grows from the follicles, and this new hair will have its natural pigment, not the bleached color.
As stated, "The results aren't long-lasting." This means the treated area will require follow-up. Experts note that "bleaching needs to be repeated once every two to four weeks to treat the new hairs that grow in."
Why Bleaching Isn't Permanent:
- Hair Growth: Hair grows continuously from the root. Bleaching only affects the hair shaft above the skin's surface.
- New Hair Pigment: The new hair that emerges from the follicle will be your natural hair color, not bleached.
- Visibility: As new, darker hair grows out, the contrast between the bleached hair and the unbleached new growth becomes visible, making the bleaching effect appear to "wear off."
Duration Factors:
The exact time frame can vary slightly based on individual hair growth rates, but generally, you can expect to see visible new growth requiring re-bleaching within a few weeks.
- Typical duration: 2–4 weeks
Unlike methods that remove hair from the root (like waxing) or target the follicle itself (like laser hair removal), bleaching is a cosmetic process that only alters the color of the hair present at the time of application.
