Beyond that, here's a breakdown of how different natural hair colors respond to bleaching:
* Light Brown to Dark Blonde: These hair colors typically bleach the easiest and often achieve desired lighter shades with fewer sessions and less damage.
* Medium Brown: Requires more effort and potentially more sessions than lighter shades. Expect to see more warm tones (orange and yellow) during the lifting process, which will need to be toned out to achieve a cool blonde.
* Dark Brown to Black: The most challenging to bleach. Requires multiple sessions with lower volume developers to minimize damage. Expect significant warmth and the need for intensive toning. It's very difficult to achieve a light blonde from this base without significant damage.
Important Considerations:
* Hair Condition: Healthy hair bleaches better. Dry, damaged, or brittle hair is more prone to breakage. Deep conditioning treatments are crucial before and after bleaching.
* Hair Texture: Fine hair tends to lift faster than coarse hair, but is also more prone to damage.
* Porosity: Highly porous hair absorbs bleach quickly, but can also become damaged quickly. Low porosity hair is more resistant and may require more processing time.
* Developer Volume: Lower volume developers (10, 20) are gentler and cause less damage, but lift slower. Higher volume developers (30, 40) lift faster but are more damaging. Never use 40 volume on the scalp.
* Toner: Toner is essential to neutralize unwanted warm tones (orange, yellow) after bleaching.
* Professional vs. DIY: Bleaching is best done by a professional, especially for drastic color changes or if your hair is already damaged. A professional can assess your hair's condition, choose the appropriate products and techniques, and minimize damage.
In Summary:
While lighter natural hair colors bleach easier, the overall health and condition of your hair are the most important factors. Proper preparation, careful application, and post-bleach care are essential to minimize damage and achieve the desired results. If you're unsure, consult a professional colorist. They can assess your hair and recommend the best course of action.
