Hair Myths Busted: What Actually Works for Stronger, Healthier Hair?

This is a collaborative post.

If we are being honest with ourselves, we’ve all fallen for the odd hair myth over the course of our lives. I know, it’s definitely true in my case…. Because you might have learnt from your nan to brush 100 times a night or a friend roped you into one with telling you about all the benefits of an avocado and beer mask. Basically, there’s no shortage of dodgy advice out there either. When you’re trying to grow healthier, stronger hair, it can be hard to know what’s fact and what’s fluff – which is why I want to set the record straight. If your hair’s feeling brittle, shedding more than usual, or just not behaving the way it used to, this post is for you. I’m busting the biggest hair myths and giving you the real deal on what actually works. So here’s Hair Myths Busted: What Actually Works for Stronger, Healthier Hair? 

The truth about hair growth

Before we start myth-busting, it is worth touching upon what your hair actually needs for it to grow strong and healthy. Hair is mostly made of keratin, which is a type of protein that grows from follicles beneath your scalp. Overall, its health depends on a combination of genetics, hormones, diet, how you treat it, and even your stress levels. There is no single miracle product to instantly bring it to full vitality, but implementing the right care routine can make a big difference to its look and feel. That said, if you’ve been doing everything “right” and still not getting results, it might be time to consider a more personalised care option, such as PHC with Gro Clinics. This solution tailors hair and scalp treatments to your specific needs, so it’s definitely worth looking into if you want a more science-backed approach to improving the health of your hair.

Now – let’s bust some myths!

Hair Myth #1: Trimming your hair makes it grow faster

I hate to break it to you, but trimming your ends doesn’t actually make your hair grow any quicker because hair grows from the scalp, not the tips.

That said, regular trims are still a good idea as they get rid of split ends, which can travel up the shaft and cause breakage. Subsequently, while trimming doesn’t speed up growth, it does help to keep your hair looking thicker and healthier overall.

Hair Myth #2: You should use shampoo every day

Unless you’re dealing with super oily hair or you spend much of your days rolling around the sand dunes, you don’t need to shampoo your hair every day. In fact, given that shampoo strips away some of your scalp’s natural oils, in some cases, washing it every day can actually do more harm than good.

To avoid your hair getting dry and dull, aim to wash it only 2–3 times a week (depending on your hair type). If you’ve got natural curls or dry ends, you can stretch it out for a bit longer. 

However, whenever you wash your hair, always use a sulphate-free shampoo and follow with a decent conditioner.

Hair Myth #3: Brushing your hair 100 times a day gives you shine

We don’t know who came up with this one, but it’s very 1950s – and, unfortunately, not in a cool retro way.

The idea seems to be based on the principle that brushing spreads natural oils from the scalp down the shaft, which is true, but it doesn’t take 100 strokes to do that. Indeed, over-brushing can actually cause friction and breakage.

When brushing your hair, make sure you use a wide-tooth comb or a brush with natural bristles. Start at the ends and work your way up to avoid pulling and snapping strands. Be especially gentle if your hair is wet. 

Hair Myth #4: Cold water makes your hair shinier

Ok, so there’s a kernel of truth in this one. Rinsing your hair with cold water at the end of your shower can help close the hair cuticle, which makes strands lie flatter and reflect more light – hence the shine.

But it’s not a miracle fix.

If you want real shine, deep conditioning masks, leave-in treatments, and heat protection work better.

Hair Myth #5: Hair oils make your hair grow

Hair oils are fantastic for moisturising, taming frizz, and adding shine, but unfortunately, they’re not going to magically sprout new strands.

While some oils, like rosemary or peppermint, can stimulate circulation if massaged into the scalp, you shouldn’t expect Rapunzel results overnight.

Instead, use oils as part of a broader routine that includes scalp care, good nutrition, and hydration.

Hair Myth #6: Stress doesn’t affect your hair

Big fat nope. Stress is a major player in hair health, and chronic stress can lead to hair thinning, breakage, and even hair loss (otherwise known as telogen effluvium).

We know life can get hectic, but if your locks are looking a little worse for wear, your stress levels could be to blame.

It is important then to take time to wind down every day. So, whether it’s a yoga session, a walk along the beach, or just switching your phone off for an hour, find ways to reduce stress and help your hair bounce back.

Hair Myth #7: You can fix split ends with products

Unfortunately, once a hair is split, no amount of serum or mask is going to glue it back together.

While products can help disguise damage and make hair feel smoother, the only real fix for split ends is a trim.

Like with anything, prevention is always better than the cure. So, avoid over-washing, use heat protectants when styling, and try not to tie your hair too tight too often.

It is also worth sleeping on satin pillowcases to help reduce friction overnight. Plus, they feel lush, too!
