How often should I treat my hair with Castor Oil if I want to grow it thicker?

well, sorry i dont actually know what castor oil is lol but what i do know is using olive oil and almond oil and massaging it in your hair and scalp and leave it on for about 30 mins then rinse your hair with cold water because hot water damages your hair. Dont wash your hair all the time cz it just makes it fall out. Another option is using egg whites, yes i knw it sounds sick!! Lol but its full of protein which is amazing for the hair, again leave it on for 30 mins then wash it out. Olive oil is very good for strengthening hair , personally ve used it and i noticed alot of change igt even made my hair grow quicker!! I hope you do try the methods out (even the eggy one!) and i hope ive helped :)
