"Air-Drying Is Better Than Blow-Drying" And 6 Other Hair Myths You Should Stop Believing

Going grey is largely determined by two factors - genetics and ageing. These cause a lack of melanin (the molecules responsible for your natural colour), which makes new hair grow in grey or white.

So once you start getting grey hairs, more are sure to follow, whether or not you pluck them out. But you should still avoid constantly plucking your hair, as this will cause your hair follicles to weaken and puts stress on your scalp, leading to hair loss, hair breakage, and even weird growth patterns and hair texture.

Hair growth happens at your scalp, so cutting the ends, no matter how often, really doesn't affect the rate of your hair growth. But experts still do recommend going for at least a light trim (known as 'dusting'), every six to eight weeks. Frayed or split ends makes your hair look thinner and encourages breakage, so snipping them off every so often keeps your hair looking fuller and healthier.

Remember back when there was the prevalent belief that you should brush your hair 100 times every night to make it super shiny and glossy? Yeah, total myth, sorry guys. Excessive brushing can actually harm your hair both short and long term.

In the short term, brushing too much causes friction which leads to frizz. And over time, excessive brushing damages your hair cuticles and causes breakage. You should only brush your hair gently and when needed, starting at the bottom and slowly working your way up to the roots.

For a lot of us, more suds and bubbles when we work the shampoo into our hair means that we're getting a deeper cleanse or that the shampoo is "working better". This is not the case as suds don't have any cleansing effects, they're just a by-product of sulfates, a common ingredient added to shampoos to give it that foaming effect. If you prefer to use sulfate-free shampoo but still want something that lathers up well, look for one that contains glycerin instead.

It's actually the complete opposite - the most common cause of dandruff is a type of yeast that thrives and overgrows in an oily environment like your scalp. A lot of people try to get rid of dandruff by washing their hair less, in an effort to avoid drying out their scalp and inducing more flakes. What you actually should be doing is washing more often to prevent oil from building up, and make sure that you're using medicated shampoo.

Supposedly, rinsing your hair with cold water closes the cuticles so that it lies flat and looks shinier. While cold water does close off the pores on your scalp, your hair itself doesn't contain any living cells, so it doesn't react to water temperature. The water temperature also has no effect on how clean your hair and scalp are. If you're looking to get smoother and shinier hair, invest in a good conditioner instead.

We've always been told to avoid blow-drying too much as the heat can cause some serious damage to your hair's surface, especially if you do it often. But it turns out that air-drying damages your hair too, and on a deeper level. Your hair swells when it's wet, and leaving it that way for a long time puts pressure on the delicate proteins that make up your hair.

Studies have also shown that towel-drying is also damaging when done incorrectly, sometimes even more so than blow-drying, as our movements tend to be too rough which can promote breakage.
