DIY beauty hacks saw a great rise since the TikTok and Instagram influencer era began across the globe.
Everyone seems to have a different solution for every skincare and haircare problem, but amidst all the hair growth hacks, rice water took the first spot.
From rice water to rosemary oil to onion juice, these three biggest viral hair hacks seem to never back down and promise longer, thicker, and healthier locks.
But which one is actually backed by science and truly works? Let’s know more.Onion juice may sound unusual to some, but it is one of the few kitchen ingredients that has actually been tested.
According to a study published in The Journal of Dermatology, it is observed that onion juice works well on alopecia areata patients, where patchy hair loss is the actual cause.
It is rich in sulfur, improves scalp health, and potentially stimulates follicles in patchy hair loss.
Onion juice surprisingly comes with strong results for patchy alopecia; however, it lacks sufficient evidence for general hair thinning.https://onlinelibrary.wiley.com/doi/full/10.1111/j.1346-8138.2002.tb00277.x?utm_source=chatgpt.com(Image Credits: Pinterest)Despite its popularity online, there is very little evidence proving that rice water stimulates hair growth.
Most claims are usually based on traditional practices, as it contains amino acids, antioxidants, and inositol, which is a carbohydrate believed to reduce hair damage.
It adds shine, improves hair texture, reduces breakage, and is very affordable to use.
However, excessive use may lead to protein overload and dryness.
It may make the hair strong and healthier, but there is no scientific evidence that it also helps in hair regrowth.(Image Credits: Pinterest)Rosemary oil has become another social media darling for long and strong hair.
In a 2015 clinical trial comparing rosemary oil with minoxidil, it was found that the combination significantly increases hair growth just after six months of use.
It improves scalp circulation, contains anti-inflammatory properties, reduces scalp irritation, and is easier to pair with other potential hair growth ingredients; however, it should always be used after diluting.https://www.allure.com/story/rosemary-oil-for-hair-growth(Image Credits: Pinterest)If you’re looking for a natural remedy with the best balance of science and practicality, then rosemary oil has to be the strongest contender of all.
Onion juice can be the surprising runner-up, particularly for people struggling with alopecia areata.
On the other hand, rice water mainly works as a conditioning treatment rather than a true hair-growth solution. (Image Credits: Pinterest)
