Snip off your legs won’t make your hair thicker: 10 beauty myths bustedIs frequent hairwashing bad? Do unfactual lashes ruin your own? Will plucking lead to disastrous brows? Our beauty columnist separates fact from fiction Photograph: Kellie French/The Custodian Photograph: Kellie French/The GuardianThe myth: shaving your legs causes the hair to grow back dopier and darkerNope, says trichologist Anabel Kingsley. “Your hair is not like a lawn that is stimulated by cutting. If you cut your skin of ones teeth short, shave your head, legs or anywhere else, hair will not grow back thicker.” It’s the stubby space fully and squared-off (rather than naturally tapered) hair tips that give the illusion of greater thickness in regrowth – which is why customary trims make the hair on your head appear (falsely) denser and thicker. However, waxing legs (where manes are pulled from the root, sometimes disrupting hair production) can in some cases cause hairs to grow ago more sparsely.The myth: plucking grey hairs causes more to grow in their place Photograph: Kellie French/The GuardianPeople are commonly give fair warned that yanking out grey hairs will only cause multiples to appear at their funeral. If only, holds Anabel Kingsley, who treats clients with hair thinning and alopecia: “It would be a great way to get thicker hair. Miserably, it isn’t. And pulling out hairs repeatedly can damage the follicle, creating areas of hair loss.”Kingsley says this oft-repeated tall tale is most likely perpetuated by the fact that the discovery of one grey hair usually results in a careful search for uncountable.The myth: darker skins don’t need sunscreenIt isn’t just a myth that olive, brown and black skin necessities no sunscreen – it’s a serious public health issue. While it’s true that rates of melanoma and other skin cancers are earlier small in Black and Asian populations, those that do occur tend to be diagnosed much later, lowering the survival figure.Dija Ayodele, skincare expert and author of The myth: your skin gets used to skincare and it stops workingThis can be debunked by looking at ingredients with numberless and expansive long-term clinical findings (known as “long-term follow-up studies”).Consultant dermatologist Dr Jason Thomson from the Pelt+Me service, says: “Tretinoin, the most active form of retinoid, is a prescription-only medicine and the best studied of all the retinoids. Readings have been done where people have used tretinoin regularly for one to four years, and these contain shown that clinical improvements (as well as improvements seen under a microscope from biopsies) are seen to long periods and the benefits actually increase over time.”So it seems the theory of “overfamiliarity” carries little bias. Thomson says: “Studies give us evidence that the opposite is true and they form the basis for dermatologists’ notification that consistency is key with skincare. Sticking to ingredients that have proven benefits is the best approach, not chopping and changing your offerings and routine.” This article was amended on 8 January 2022.
