There are many times we become frustrated with out natural curly hair. You've done everything to make sure you hair can stay moisturized as far as keeping up with shampoo and co-washing treatments, deep conditioning treatments, protein treatments, sleeping with a night cap/silk scarf, and sealing hair. Yet the frustration still remains and not knowing why the hair still feels dry after moisturizing.
Three reason why hair maybe be dry even after moisturizing. Here are some things that you could do to help your hair stay moisturize.
The LOC method
LOC method is a technique of product layering that you use in your hair to help to retain hairs moisture for a longer duration.
1) "L" is for liquid. It can be water or a leave-in moisturizer
2) "O" is for oil. Select an oil of your choice ,such as olive oil. You then layer oil on top of your leave-in.
3) "C" is for cream. This is any hair butter that is thick consistency. Butters or hair creams that you have for your hair care regimen. You would layer lastly on your hair. By layering your hair in this order with products in the LOC method, this is helping you to keep your hair moisturized longer.
Also, you can do the LCO product layering. Test and see which method works best for you.
For some people certain products weighs their hair down a little bit too much. Its best to try different types of oils, creams, or leave-in conditioners you're using on your hair. Both methods work and will help hair not to be dry as often when used on a regular needed bases.
Use oils and butters to seal natural hair
I would suggest is that you use heavier oils. Heavier oils, such as castor oils, coconut Oil, Castor Oil, Olive Oil, Avocado Oil, grape seed oil, and Jojoba Oil. Butter, such as, shea butter, mango butter, and cocoa butter. For some people castor oil is a little bit heavier on the hair Try different oils or butters to figure out which is going to stay on your hair and help your hair not to be greasy or weighed down, but to help you to retain hair moisture for a duration. Let me let you in on some important information. When you put oil on top of wet hair it slows down the evaporation of water from leaving your hair. Let say you wash your hair and you do not put oil on your hair some type of cream to keep water locked in your hair. You hair will get drier a lot quickly than it would if you will put oil on your hair it's going to take a longer amount of time for that oil to slide down off your strands allowing moisture to leave your hair. Sealing hair with oil and butter is very beneficial to lock in the the water molecules a bit longer, therefore retaining moisture.
