Alongside beauty and diet tips, social media is rife with viral hair growth advice. With suggestions including Kim Kardashian’s rice water hack and Cardi B’s onion water remedy. But amid the frenzy of hashtags ( #hairgrowth has over 579,666 posts!) and DIY tutorials, discerning fact from fiction can be a little confusing. We caught up with Hair and Skin Science Chief Medical Officer Dr Min-Qing Lee who analysed each hack and revealed the ones he recommends. As well as the five biggest TikTok hair growth myths debunked!
1. Collagen – Debunked
With over a million posts touting collagen’s hair growth prowess, it has become a staple recommendation on TikTok. However, Dr. Lee, urges caution. While collagen offers various health benefits, its efficacy in promoting significant hair growth remains unproven by scientific evidence. Dr. Lee advises incorporating collagen-rich foods into one’s diet for overall wellness instead of relying solely on supplements.
2. Rosemary – Recommended
In contrast to collagen’s uncertain standing, rosemary (yes, the same herb that pairs perfectly with a Sunday lab roast) emerges as a TikTok trend backed by science. Whether applied topically or ingested, rosemary has demonstrated promising results in the potential to improve circulation and stimulate hair growth. Dr. Lee advocates for the use of rosemary oil for scalp stimulation – highlighting its potential to enhance blood flow to hair follicles. However, he does advise users conduct a patch test beforehand, especially for individuals with sensitive skin.
3. Aloe Vera – Debunked
Despite its reputation for soothing and hydrating properties, aloe vera’s ability to promote significant hair growth remains dubious. Dr. Lee remains skeptical, citing limited scientific evidence to support its role as a hair growth stimulant. Nonetheless, aloe vera can still contribute to scalp health and hydration, albeit without substantial hair growth benefits.
4. Retinol – Debunked
Often celebrated for its skin-rejuvenating effects, retinol has also found its way into hair care discussions. However, Dr. Lee cautions against its use for significant hair growth, citing insufficient evidence. While retinol may indirectly support scalp health and cell turn over, its role in promoting hair growth lacks substantial scientific backing. Additionally, individuals with sensitive skin or those who are pregnant or breast feeding should exercise caution when considering retinol-based treatments.
5. Caffeine – Recommended
Surprisingly, your morning cup of coffee might do more than just perk you up. Caffeine’s ability to stimulate hair follicles has earned it a place as a viral hair growth hack on TikTok. Dr. Lee supports this trend, citing scientific evidence that highlights caffeine’s potential to improve blood circulation in the scalp. However, he advises against overuse and recommends latte lovers consult a dermatologist, especially for individuals with caffeine sensitivity or preexisting scalp conditions.
6. Micro-Needling – Recommended (in a professional setting)
Micro-needling, often accompanied by procedures like PRP/PRF, has gained traction as a hair growth hack on TikTok. Dr. Lee recommends micro-needling in a professional setting, emphasising the importance of proper instruction to avoid adverse effects such as infection or scarring. While some studies suggest potential benefits, evidence of its effectiveness for hair growth is mixed. Individuals should exercise caution and seek professional guidance before they attempt to micro-needle at home.
7. Hibiscus – Debunked
Hibiscus, touted for its antioxidant and moisturising properties, has garnered attention as a potential hair growth aid on TikTok. However, Dr. Lee advises against relying on hibiscus for significant hair growth, citing limited scientific evidence. While it may improve the overall condition and appearance of the hair, its efficacy as a hair growth stimulant remains unsubstantiated. Nonetheless, individuals can still enjoy its nourishing and conditioning benefits as part of their hair care routine.
8. Specific Ways of Hair Washing – Recommended
While various hair washing techniques flood TikTok feeds, their direct impact on hair growth remains uncertain. Dr. Lee emphasises the importance of proper hair washing techniques for maintaining scalp hygiene and overall hair health. While washing alone may not directly stimulate hair growth, it plays a crucial role in scalp hygiene and hair follicle health. Individuals should adjust their washing frequency and product selection based on their hair type, scalp condition, and lifestyle factors.
9. Store-Bought Hair Serums – Recommended
Store-bought hair growth serums, containing ingredients like minoxidil, have gained popularity as a convenient solution for hair loss or thin locks. However, its effectiveness may vary depending on the formula and active ingredients. Dr. Lee recommends serums containing clinically proven compounds like minoxidil for individuals experiencing hereditary hair loss or thin hair. However, he advises caution and recommends users consult a dermatologist before use, especially for individuals with sensitive skin or allergies.
10. Castor Oil – Debunked
Despite its recent surge in popularity, castor oil’s efficacy in promoting significant hair growth remains questionable. Dr. Lee advises against relying on castor oil alone for hair growth, citing limited scientific evidence. While it may moisturise the scalp and nourish hair follicles, its role as a hair growth stimulant lacks substantial backing. Nonetheless, individuals can still benefit from its hydrating properties as part of their hair care routine, especially when used in conjunction with other treatments.
