Coloring....that can't be screwed up at home cause my hair is medium brown naturally?Is there any shampoo to keep my blonde highlights blonder longer?
the best product to use is redken for color hair if you are coloring your own hair i recommend going to a beauty supply house that sales to the public it does sound like your hair is not grabbing on to the color this is why your hair is fading this is caused from your cutical leyer not closing and that is caused from over prossesing you need a deep conditioner to get that cutical closed switch to a 30% bleach if you are using a 40% would help if i new if you had breakageIs there any shampoo to keep my blonde highlights blonder longer?
Yes, I use a shampoo by John Freida. The name of it is John Freida Collection, Sheer Blonde. This shampoo comes in all 3 types of hair colors. I use the one for Blonde hair. I use this shampoo all of the time and it helps keep the blonde highlights lighter and doesn't let them fade. It also comes in the conditioner too. I love this shampoo and can use it every day. It doesn't dry your hair or anything. I buy mine at Walmart of other stores like that. Good Luck!
john freida's sheer blonde. it is suppossed to bring out the blonde in you and will keep you that way without darkening your hair. also, john freida sells a color enchancing tub of subtle natural dyes, and keeping those highlights.
there's a lot of color shampoos and conditioners. sheer blonde by john frieda is a good one. also you can get color enhancing kits at the supermarket that are pretty easy to use. hope that helped. :)
Of course! I love Herbal Essences Color Me Happy shampoo %26amp; conditioner, it really helps your color last.
