Troubleshooting Hair Problems - Does your hair need protein or moisture?
Protein vs. Moisture is a balance, but when you get it right, your hair looks great and is easier to handle.
An easy test to know if your hair is lacking moisture or protein is to take a couple shed hairs after a shower - you can also use a few hairs from your brush and get them wet. Wrap one side or the ends around a finger, and the other ends on a finger of the other hand and slowly stretch/pull them. If your hair stretches 30%-50% it is normal. Less and it breaks easily; then you need moisture. If it is very stretchy or almost gummy you need protein.
If you need moisture it's the more common and easier of the two to correct. Try a deep conditioner like Aussie's 3 Min Miracle once a week or a Hair mask with any oil once a month.
If you need protein you have quite a few options. You can try to add more protein in your diet, look for hair products (shampoo and conditioner) that contain keratin or any of the ingredients listed on this page or get a leave in protein treatment (Giovanni Direct Leave in as an example). Just be careful not to go overboard with protein. It can make your hair feel dry - like straw if you go too crazy...
Coconut Oil helps to add moisture in hair masks and at the same time helps your hair to retain protein. If you are right in the middle, or need protein this would be a good product to add into your hair routine. I have noticed that if I use too much coconut Oil in my hair masks that my hair gets dry and I need to up the conditioner for the next week or so. Some hair types are more sensitive to protein than others.
