Gray Hair and Baldness: Coconut oil is also beneficial for preventing baldness and gray hair. Try mixing Bhringraj or Eclipta Alba leaf juice with the oil and apply this on the scalp and hair. Coconut oil is widely available in the market.
My mom would try to put coconut oil on my hair when i was little but i would run away because i did not like the smell of it, now i have thin and graying hair at 32. I wish i did not run away then, but i have now started applying coconut oil in my scalp and hair. Hope it would still work.
