What shampoo makes your hair grow faster and longer walmart

Hair vertically challenged? If so, you’re far from alone. It's the reason why myriad hair growth shampoos, gummies and supplements have flooded your local Boots in recent years.

And yet with so many formulas out there promising to give you strands long enough to rival a Love Island contestant, how do you know if they really work? Or, rather than truly having the ability to add inches to your strands, are these products money down the drain?

WH spoke to the experts and put products to the test in the WH Lab to find out if these next-gen shampoos are miracle workers or marketing BS. Stay with us for the honest truth.

Skip straight to the products that work.


What makes your hair grow faster?

First things first, it’s important to assess why your hair isn’t growing as you’d like it to. Of course, if it’s hair thinning or loss you’re dealing with, then it’s best to consult a doctor. (If you’re noticing too much hair in your hairbrush, or think you might be struggling with a medical condition like alopecia, there may be a prescription-only solution that’s open to you.)

That said, if you’re simply struggling to grow out a bad haircut or get your ends to creep past your shoulders, a hair-growth shampoo might be your first port of call.

When it comes to environmental factors, there are many things that could be slowing down your hair growth.

There is some evidence that sulphates (lather-inducing detergents used in many mainstream beauty products) can irritate a sensitive scalp. And, when it comes to lengthy hair, this is an issue. 'The scalp is the bedrock for the hair follicle, and if it is not in good condition the chances of you experiencing problems with hair growth and health increase significantly. In fact, research has proven that a flaky, itchy scalp can cause and/or worsen hair loss in certain individuals, Anabel Kingsley, Trichologist at Philip Kingsley, tells WH.

Or perhaps it’s the way you’re brushing your lengths: attacking tangles with a hairbrush is likely to snap your strands, which results in hair that just won’t reach the mile-long lengths of your dreams.

What foods help hair growth?

Plus, ensure that your diet includes plenty of hair growth-supporting Biotin, AKA water-soluble vitamin B. You can find this in egg yolk, yeast and wholegrains – or pop a supplement.

Now, onto the big question.

Do hair growth shampoos really work?

According to aesthetic dermatologist and hair-restoration surgeon Dr Max Malik, hair growth shampoos may not live up to the hype.

‘As far as over-the-counter options go, shampoos and other treatments are very widely sold and it’s a huge industry. However, there is actually very little evidence in support of these treatments,' is his take.

Kingsley agrees that the buzzy claims made by hair-growth shampoos may be misleading, drawing attention to the many factors that can hamper their success.

‘It’s important to note that the effectiveness of a product is not just reliant on the ingredients inside: it’s heavily dependent on the concentrations of the ingredients, the quality of them and how they are formulated into the product,’ she explains.

What’s more, Kingsley suggests that the way these shampoos are used may determine whether they work or not.

‘For instance, many ingredients need to be left on the scalp for an extended period of time and/or be used daily, in order to be effective.’

What is the best product for hair growth?

However, Kingsley does highlight several ingredients contained in some hair growth products, that can help to optimise the health of your scalp, which can in turn support healthy hair growth.

These include:

  • menthol (a stimulant)
  • piroctone olamine: an antimicrobial that helps to clear flaking and itching.
  • caffeine and peppermint oil can help boost circulation at the scalp
  • amino acids and proteins can strengthen the hair strands

    Effectively, the most effective ‘hair-growth’ shampoos don’t actually give your hair a growth spurt, but rather play a supporting role in ensuring your lengths reach their natural full potential.

    So, there you have it: nothing on the shelves will give you hip-skimming hair in a fortnight, but you can ensure your strands are growing at optimal natural rate. Scroll down to discover the best ‘hair-growth’ shampoos for the job.

    How we test

    Every product awarded a Women's Health Lab logo below has been tested by a panel of 700 testers, all with self-diagnosed mild to extreme hair loss or thinning.

    Each tester tried a targeted shampoo and conditioner set for one to two months. The products all aimed to correct one of the three main causes of hair loss: breakage, thinning, and lack of root or scalp stimulation.

    Testers made a note of any changes to their scalp or hair’s condition, as well as how their hair felt after each wash. The panel included women with a range of hair types, from straight to afro hair.

    In the Women’s Health Lab, our experts tested anti-breakage shampoos by combing through hair switches treated with the product(s) and comparing them to untreated switches. The easier the treated switches were to comb, the lower the risk of hair breakages and fallout in real life.

    For those shampoos with thickening and root-stimulating claims, our in-house testers used a HairMetrix machine to analyse the effect each set had on hair thickness and density.

    But that’s not all! Our Women’s Health beauty editors have also suggested some hard-working products that get results – find them under Editors' Picks.
