Thick, swishy, glossy hair is the Holy Grail for most of us.
However, as we get older – or go through hormonal changes like pregnancy and breastfeeding – many of us will experience our hair thinning.
Stress, a bad or very restricted diet can both also contribute to thinning hair, as can certain medications.
And while the problem sometimes corrects itself with time, feeling your hair get thinner can be very traumatic for many, and can leave us feeling self-conscious.
However, if you have been struggling with thinning hair, you might want to check this viral TikTok video out, with a simple DIY solution that promises to get your hair growing thicker again.
In a recent video that's garnered more than 3.8 million views, TikTok user @kaligirly shared the simple recipe for an at-home hair loss treatment she swears by.
And the method is pretty simple: Simply steep some rosemary tea, let it sit in the fridge for an hour, then spritz it all over your hair.
"A great choice for hair growth"
Now, we all know you can't believe every beauty hack you read on the Internet, but as it turns out, this particular hair-loss potion is actually pretty legit.
According to a clinical review published in BMJ, rosemary may help with hair growth when massaged into the scalp daily.
In addition, a 2015 study published in SKINmed Journal found rosemary may help protect against hair loss. "Rosemary is a great choice for hair growth and hair thickness because the essential oil can repair, stimulate, and regulate cells. That means it can help to reduce or balance oily discharge at the hair follicles," adds certified aromatherapist Caroline Schroeder.
How to DIY rosemary hair spray
1. Get a spray bottle
This formulation works best when sprayed all over the hair. So before you start brewing, make sure that you have a spray bottle handy so that you can properly distribute the rosemary tea to your scalp and strands.
2. Boil water
This part is super simple. Put about 2-3 cups (depending on the size of your spray bottle) into a pot and turn up the heat. Wait until the water is bubbling before moving on to the next step.
3. Add the rosemary
Once the water has reached a boil, pop in a few sprigs of fresh rosemary (which you can pick up at your local grocery store). Then, turn off the heat and cover the pot with a lid.
Let your concoction brew for about an hour. You'll know it's done when you see the water starts to turn red.
5. Cool and transfer
Once you've let the formula sit for long enough (at this point, it should be cool), carefully transfer it into your spray bottle. To make this process easier, use a funnel to ensure that you get all the liquid inside the bottle and avoid a mess.
6. Store in the fridge
Keep your spray bottle in your fridge. This will keep the spray from expiring for about a week.
How to use
When it comes time to use the formula, simply spritz it onto your scalp and strands and let your hair airdry. If you want a more potent treatment, hair care pros suggest mixing a few drops of rosemary essential oil with a carrier oil (like jojoba or coconut oil) and massaging it onto your scalp before bed.
And although you probably won't see results overnight, after a few weeks of using the spray, you should start to see a difference in the thickness of your hair.
