To grow out bleached hair and get back to natural, you can either have your hair tinted back to natural or grow out the blonde without dyeing. Hair that's chemically overprocessed and brittle doesn't react well to tint-backs -- or you may lack the funds to get it done. Growing bleached hair without coloring it requires slight adjustments to your beauty routine that maximizes the hair's growth and minimizes damage to it. It's not for the faint of heart, so focus on that healthy natural hair you'll get through the grow-out.
Pop daily hair vitamins. They're marketed as such, they're sold at major drugstores and they contain B vitamins and antioxidants designed to boost hair growth.
Protect bleached blonde hair from getting damaged or dried out via excess washing. First, try to stretch the number of days you go in between shampoos. Then cut down to a gentle shampoo that's meant for dyed hair. If your hair is really damaged, dilute the shampoo with three parts warm water and wash with that, slowly working up to straight shampoo. Lastly, wash with lukewarm water not hot, since hot water dehydrates locks.
Condition hair to get moisture back into it. Use rich conditioner each time you shower and follow up with a weekly deep conditioning treatment or hot oil treatment, leaving the treatment on for 20 to 30 minutes before washing off. Hair that lacks moisture breaks more easily, leaving you stuck in a rut. As you increase the hair's moisture, less will break so you'll actually grow those tresses.
Style your hair without the use of curling irons, flat irons or hair dryers. All of these fry your hair, and brittle bleached blonde hair can break and dry out more. Dry your hair naturally, or set curlers to curl it.
Visit your stylist every six weeks to get the blond trimmed off. As your natural hair grows in and you cut off the blond, you'll notice the new hair is healthier.
If you don't like the look of your mane while the blonde grows out, come up with creative ways to hide it. Wear bold hair accessories and fascinators that call attention away from the color of your locks, or put hair up. Cover your locks with a hair scarf tied in a bandana or flat style.
