A good bet would be a glaze. John Freida brand sells one and from my own professional experience working in the cosmetology field it would be good to head to Sally"s beauty supply. Look for one by Loreal or Clairol. They work great. I use them all the time. Also it would be good to let hair air dry when possible. If it isnt possible to air dry use a heat protectant spray or serum before you use a heat tool. The best products for your hair type are creamy consistency with conditioning additives. Dry hair tends to have a hair shaft that is inflated. Curly and bleached hair tend to have this problem more often. Its important to use products that contain low alcohol as it dries the hair out even more. You want things that will help seal the hair shaft. You can also find hair masks and deep conditioners for your specific hair type. It helps if you keep the ends trimmed and after you trim the ends to apply the hair mask and then wrap your hair in a towel or wear a shower cap with a cotten liner for at least 25 minutes. If you want to go natural try a mashed avocado and banana hair mask. There are alot of recipes online and product info. Hope that helped!

You can use a conditioner that contains panthenol, amino acids, silicones and also mineral oil. The mixture of these ingredients will help to toughen, moisturize, smooth and also protect your hair. Ensure to consult with a hair stylist for more help and you can find out more details on http://www.ehow.com/list_7304578_solutions-heat_damaged-hair.html.

You can buy a hot oil treatment at a beauty supply outlet or mayonnaise worked into hair and left for about 10 minutes and then rinsed well also works

let it grow and cut it?

If it was damaged by a straightener or curler. STOP STRAIGHTENING IT.

Then continue to wait a few days, wash your hair as normal, brush it and continue on with life.
AND STOP STRAIGHTENING IT.

Straightening hair can cause horrible damage to it!

I bought an olive oil treatment that works really good but it makes your hair really oily looking so I apply it and then take a shower an hour later and it works great! the brand is Proclaim and they have shampoos, conditioners, lotions, sprays, and gels and all of them are made from olive oil and replenish your hair.

try not to flat iron it a lot. use one of those repair shampoos

I have the same problem , and i just put olive oil in my hair and then wrap it and leave it alone overnight so all the oil gets on the wrap and the oil will soak into your hair ,and it will be dry , smooth , and shiny for the next day !!

if your hair is thick and curly like mine you do not want to use any conditioner that says "weightless formula" or some crap like that. make sure its a good moisture conditioner and use it generously!!! and dont brush your hair when its wet. it can possibly damage it.

I recommend the product that I use to restore the damaged hair, it's Pro Naturals Moroccan Argan Oil, it's amazing, protects the hair, makes it stronger and keeps the hair shiny, soft and healthy. :D If you are interested you can check it out at safrons .com .
