Beat the egg well, you don’t want clumps stuck in your hair, and mix into the mixture.
Mix in castor oil.
Apply the mask throughout your hair, maybe even taking a comb and combing it though. You want the mask to reach every strand! (I used my hands to apply it, and there was NO WAY I was getting a comb through my naturally curly hair!)
Pin your hair up, and put a shower cap on. Wrapping it in a towel will also help, but sometimes the towel awkwardly slips around, so if you need to skip it that’s ok.
Leave the mask in for at least 20 minutes. I left mine in for almost an hour. :)
