I have 3A type curly hair. I want to go blonde, but wondering would the bleach be damaging my curls
Everyone's hair is different so some can bleach and have no problems while others have damage and loss of curl pattern. When I lightened mine on my own with a box color, my curls loosened and in some places became completely straight. Luckily that only happened to the colored parts and once my hair grew out, the new growth was back to normal. I would definitely suggest that you go and have it professionally bleached and colored at a salon.
Like the previous poster said everyone's hair is different. But make sure you care for your hair well before and after to minimize breakage (ie: avoiding heat/ maybe sulfates). Maybe a protein treatment beforehand, and a cowashing routine afterward would be the extra care your hair needs.
