If you’ve ever gone down the “natural hair care” rabbit hole on Instagram or YouTube, you’ve definitely seen rosemary oil and tea tree oil everywhere. One reel shows someone swearing by rosemary for regrowth, the next has tea tree oil fixing dandruff overnight. Even our mums and grandmothers have their own oiling hacks.So what’s the truth? Does rosemary oil really help your hair grow? Is tea tree oil just for dandruff? Or are they meant for totally different hair problems? Let’s clear this up – no miracle promises, just real talk, with a little Indian context.
Why are we so obsessed with oils for hair growth?
In India, oiling your hair isn’t some fancy self-care trend. It’s what we’ve grown up with. Sunday champi, coconut oil in winters, onion oil experiments during hair fall phases – we’ve tried it all. Somewhere along the way, we started believing that oil alone = good hair.But hair growth isn’t that simple. Your hair depends on things like:How healthy your scalp isBlood flow to the rootsHormonesWhat you eatHow stressed you areYour genesRosemary oil and tea tree oil don’t magically grow new hair overnight. What they do is help fix scalp issues and improve the conditions your hair needs to grow better.Rosemary Oil: The growth favourite everyone talks aboutRosemary oil comes from the rosemary plant, and it’s become the star of the “natural hair growth” crowd.
