* Bleaching lifts natural pigment: Bleaching removes the natural melanin in your hair, leaving it very light and often with a brassy or yellow tone. It doesn't add any color, just removes it.
* Bleached hair is fragile: Bleaching weakens the hair shaft, making it more prone to breakage, dryness, and damage.
* Unwanted yellow tones: Bleaching alone will leave you with very light, sometimes even white, hair, but the undertones will likely be yellow or brassy. To achieve a desired color, you'll need to tone or dye over the bleached hair.
What you can do:
* Use a color remover: If you want to remove color without bleaching, consider a color remover. This product works to lift existing color without lifting the natural pigment as much as bleach. However, it may not remove all the color, and it can still cause damage.
* Use a toner: A toner can help to neutralize unwanted brassiness and yellow tones in bleached hair. It can also be used to achieve subtle color changes.
If you're considering bleaching your hair, it's best to consult with a professional stylist: They can assess your hair type and condition and recommend the best approach to achieve your desired color.
