Yes to the above... and a good thing about biotin is that your body only absorbs what it can use, so over-doing it is easy to avoid. Also, if you wash your hair daily, massage coconut oil into your scalp every night before bed then wash it out in the morning. I do that often but cover my pillow with a towel or case I don't care about just in case.
Lastly, what works well for me is using a mask. The first one: mashup 1/2 avocado and 1/4 c. coconut oil. Apply, comb out excess and rinse.
Second one: 1 egg 1/4 cup yogurt 1/4 cup honey 1/4 cup olive oil.\
What to do: 1. Beat the eggs until they become frothy and add in the olive oil.
2. Whisk until it's fully blended together and add in the yogurt, mixing until it's a creamy consistency. Then add the honey.
3.Spread the mixture from your roots to your ends, combing it through.
4. Wrap your hair in a warm towel for twenty to thirty minutes before your rinse it out and shampoo.
Hope this helps!
