My hair is quite badly damaged, it's been dyed and re-dyed so many times, it's suffered years of GHD abuse and a bit of overwashing and it's permanently in a dry, damaged, fragile state. So I was just wondering is there anything, any product, that can REALLY rejuvenate the health of your hair as in properly repair it? Cutting it off is not an option!!

I use shampoos and conditioners designed for dry/damaged hair (at the minute I'm using the Garnier Ultimate Blends with shea butter in it - so lovely!) and I occasionally use hair masks and macademia oil. I'm getting into the habit of covering my hair in coconut oil every night and washing it out in the morning and while it makes my hair lovely and soft, it doesn't seem to be doing much for the damage. I also use Orofluido oil heat protect spray every time I blow dry or straighten it which is meant to have a high heat protection in it (I previously wasn't using heat protection).

Has anyone any tips or tricks for repairing the hair? What I'm doing doesn't seem to be doing much so really need some new advice!!

There's not a lot you can do to repair it, but you can help the appearance a little. Getting the ends trimmed on a regular basis is the best bet. I know you don't want to cut, but really it's the only answer. In the meantime, coconut oil is great, as is shea butter. I don't know about the ingredients in Garnier, but I'd avoid anything that has stuff like sulphates, silicone, etc. A lot of shampoos that contain those ingredients may seem to help your hair in the short-term but end up doing more damage in the long-term. You can take vitamins to help with strong (new) hair growth, but basically once a hair has left your head it's dead and there's little you can do about it's condition.

My hair was damaged by having my straighteners too hot and I was advised to use Kerastase Resistance products which worked wonders.
I still use them and my hair is highlighted, washed, dried and GHD's daily and is in very good condition

How often do you get your hair cut? I now you said you don't want to get it cut but as another poster said if you get it cut regularly you will only need the ends trimmed.

If you haven't had it cut for years I think you're destined to have forever damaged hair unless you get it cut off - you can't 'heal' damaged hair just improve it's appearance. Might be worth popping to the hairdressers to see if they can give you an opinion on how much you'd need off if this is the case, as otherwise your hair is going to just continue getting worse - would go either way and at least get the ends trimmed!!

Also if your hair is damaged it will probably stop growing if you don't want it cut because you're trying to grow it.

You don't need to cut it off but a cut is required otherwise all you're doing is conditioning ends that are damaged and nothing will happen, you'll just be wasting products; get rid of them. Your hair will still grow from the roots but you won't retain any of that growth because the ends are likely to be weak and split, and they will simply break off. A good cut will enable you to start the repairing process on a clean canvas.

You need to strengthen the hair with protein treatments. Joico does a very good one called K Pak. Use it, or similar every week until your hair begins to feel stronger. The hair needs nourishment and moisture also, so use a good moisture treatment. Oil is good but I would personally use both conditioner and oil together overnight, at least once a week for a few weeks.

Make sure that your diet and water intake is sufficient.

Suffice to say, try and lay off the heat. The hair can only take so much heat regardless of how much protectant you use.

I use oil with keratin which has helped quite a bit.

It depends on the extent of the damage, I think. I've messed mine up badly a few times, and found that leaving a really goo, thick conditioner or conditioning treatment on overnight helped a lot. If it's really bad though, nothing but scissors is going to sort it.

The important thing is not to damage it any more, and gradually it will grow out, as long as you keep trimming the ends.

My favourite products are Kiehls silk straightening balm or Organix spray with argan oil before blowdrying and straightening. Mine is highlighted every 8 weeks and dried and straightened daily, and has remained in really good nick since I've been using them.

I would give this a try. It's cheap and if it doesn't work for you not much lost.
I use it if I overdo the straighteners . Leave it on overnight ( wear a shower cap ) and you should see a big difference. My hair feels great after I've used it.

Try Ktc Coconut oil you get it for 2 quid at morrisons and the smaller one is sometimes cheaper...about £1.10....

give yourself a massage with it regularly....let it soak in your hair for a day or so and slowly slowly your hair will be repaired.....theres a lot of tips on the net....I always find coconut oil to help rather than any other expensive or bargain hair masks I've tried

Hair from root to ends is basically dead.

After my op in October 2013 I had intense radiotherapy and this affected my hair and skin very badly. My hair felt "fried", was extremely brittle and kept breaking. My hairdresser told me that the best thing I could do was to keep trimming the ends but at the same time invest in a good hair product and she recommended that I buy Pro Naturals Hair Repair System - which contains argan oil. I am thankful that I did. It has taken several months to bring my hair under control but I have turned the corner and can honestly say that I no longer have brittle, breaking, lifeless "flat" hair. My hair today is very shiny, looks extremely healthy and no signs of split ends or being brittle.

My hair has broken from too much hair dye and use of straighteners. I don't want it cut either but it's the only way. Just keep getting the ends trimmed until the damaged hair has grown out. I do use John Frieda serums and an overnight product which help it to look smoother.

Try some Philip Kingsley elasticiser which is available on many beauty websites including Feel unique.com. It's a pre shampoo treatment which doesn't leave your hair greasy afterwards and you can leave it on overnight if you want to and shampoo out the following day.

Aveda do some good conditioners for dry/damaged hair.

Stay away from the hairdryer and let your hair dry naturally and get regular trims from the hairdresser every 6-8 weeks.

I've dyed my hair quite a bit in the past and have had highlights too but I have really good healthy shiny hair but I probably only use a hairdryer once a month and I pretty much wash it every day.
