Amazon shoppers are going wild for the miraculous effects of a hair growth shampoo which has garnered glowing reviews for battling with thinning, fine, and damaged hair. The Grow Me Shampoo by Watermans, which won the Queen's Award, is made in the UK and packed with a potent blend of ingredients including biotin, argan oil, niacinamide, caffeine, lupin protein, and allantoin for renewed growth.

Boasting anti-inflammatory qualities, the shampoo also promotes a healthier scalp and even claims to reduce greying. Although normally retailing at £14.95, it's currently available on Amazon for a slightly reduced price of £13.95, and at Boots for £13.99. The description touts: "By stimulating the deep dermal vascular plexus, it ensures optimal nutrient delivery to your scalp. You may even experience a mild, itchy tingling sensation-an indication that the formula is actively working to help you grow strong, resilient hair."

Raking in an impressive 4.2 out of 5 stars from over 12,957 global ratings on Amazon, the Grow Me Hair Growth Shampoo is earning accolades from happy customers. One satisfied user, Bethany, shared: "Bought for my partner after his hair transplant, it was recommended by the doctor who performed the procedure. Has worked amazingly - smells nice and does the job. Used on my own hair a few times which leaves it feeling soft - would recommend."

Another delighted shopper added: "I cannot recommend the Grow Me Hair Growth Shampoo enough. After trying countless products for my thinning hair, this one truly stands out as a game-changer. Within a few weeks, I saw less hair fall in the shower and more volume overall. My hair feels thicker and healthier, and I've even noticed some regrowth in areas that were thinning.", reported Liverpool Echo.

On the contrary, not everyone is convinced, with a buyer remarking: "This is an ok shampoo. I suppose I was looking for a miracle or something as I said it's ok as a shampoo found to be no different than shampoos you can buy from my local shops."

Echoing the sentiment of mixed results, Danielle admitted: "I will be honest I held out for a few months before doing this review, I saw no difference and ended up resulting in me buying another brand. However, great smell and leaves my hair feeling smooth."

But one ecstatic user shared: "This shampoo is absolutely amazing. You do have to leave it on for three to four minutes but it's well worth it. Just from one use my hair appears thicker and bouncier. I've probably used every shampoo on the market but this one beats them all."

The effectiveness appears to vary among consumers, yet for those still in search, Boots offers other options like the discounted Nioxin Anti-Hair Loss Shampoo 240ml (£21.80, was £27.95) and Pantene's Hair Biology Menopause Shampoo For Thinning Hair (£4, was £8) at tempting prices.
