Yes coconut oil can help to prevent hair loss as well as help regrow your current hair.
Coconut oil helps prevent hair loss and helps to regrow hair because coconut oil contains natural antioxidants and nutrients including vitamin E, vitamin K and iron.
Those nutrients and vitamins are all essential to keeping your hair from falling out and keeping your hair healthy as well.
You can warm the coconut oil up and then massage the warm coconut oil into your hair and then leave the warm coconut oil in your hair overnight while you sleep.
I used coconut oil with great results at regrowing lost hair and I haven't lost anymore hair after using the warm coconut oil in my hair at night.
I use coconut oil in my hair once or twice per week and then use a shower cap at night to keep the coconut oil from getting onto my pillows and bed.
