👉 Unbleaching is a cosmetic treatment that involves removing all of the existing hair from your scalp, using chemicals or heat to remove it. This process can be used on both men and women. Unbleaching can help with a variety of skin issues such as dandruff, dryness, and hair loss, but it also can be used for other cosmetic purposes such as improving the appearance of scars, wrinkles, and uneven skin tone.
