I need some tips on good products and ways to restore natural moisture to your hair if its VERY dry.

I recommend doing a deep conditioning treatment twice a week to restore moisture in your hair and repair some of the damage. You can also use a leave-in conditioner, it will keep your hair from looking dry and frizzy.

I've read your other post regarding sun-in bleach. If your hair is in bad condition, I advise you not to color it. It would be best to go to a salon and have them do a color correction process.

You could do with finding a product called Indola Vitamin Spray - You can get it here in the UK but not sure in the USA - but try and have a look for it - It is a vitamin leave in conditioner - IT IS FANTASTIC -
I use it on my clients who are having a perm or colour to replace any porosity lost.
