From stress and heat damage to the natural effects of ageing, hair thinning is a frustration many of us face. But a cult-favourite shampoo from Philip Kingsley is changing the game. Labelled "outstanding" by shoppers of all ages, this scalp-boosting Philip Kingsley Density Hair Thickening Shampoo is delivering visible new growth and thicker, fuller hair.

The results speak for themselves as a customer in her early 70s shared: "I have fine, naturally blonde hair... but just lately, it has started thinning. Philip Kingsley Density Hair Thickening Shampoo and conditioner have really helped, and they are a joy to use."

While the price tag sits at premium territory - £32 for a one-time buy or £25.60 on a subscription sale - its clinical-grade performance may justify the splurge. Engineered to combat hair shedding, the shampoo combines powerhouse ingredients that hydrate and smooth the hair fiber from the inside out, all while offering calming relief to easily irritated scalps.

Formulated to cleanse the scalp and fortify each strand, the Philip Kingsley Density Hair Thickening Shampoo helps create volume, resulting in a fuller-looking finish, making it a perfect option for those experiencing thinning hair.

Its formula is infused with hydrolysed pea peptides, recognised for their antioxidant, moisturising and smoothing properties, contributing to hair that looks healthier and more resilient, reports the Manchester Evening News.

As well as peptides, the shampoo formula features hyper-branched polymers (supporting structural repair, reportedly) and strengthening molecules, and is trichologist-approved. While the reviews for this shampoo are overwhelmingly positive, research conducted by the brand validates its effectiveness.

It discovered that, when combined with the Density Conditioner and Protein Spray - which the brand advises for best outcomes - 92% of participants reported their hair felt more textured, while 25% noticed increased volume after just one use.

Customers can purchase the shampoo and conditioner as part of a bundle which is on sale for £56.32 from £64. For a more budget-friendly option, the Noughty Get Set Grow Shampoo and Conditioner Duo Bundle (£17.98) provides impressive volumising results without quite as much of a premium cost.

Developed with a combination of organic pea sprouts, green robusta coffee beans, piroctone olamine and hydrating hyaluronic acid, it helps leave hair feeling smoother, healthier and noticeably fuller.

Meanwhile, Absolute Collagen's Thickening Collagen Complex Shampoo (£18) is reportedly the 'UK's first collagen complex formulation shampoo that works to nourish, thicken, and volumise thinning hair, while maintaining that all-important lightness'.

That said, boasting an impressive 4.5 star rating out of five, the Philip Kingsley Density shampoo has won fans for its ability to minimise breakage and leave hair feeling noticeably stronger.

One delighted reviewer shared her personal hair journey, crediting the formula with restoring her locks to how they were 'in my 20s'. She said: "During the menopause my hair was coming out and breaking, however two months of use of the Density thickening shampoo and conditioner my hair is thicker and fuller like when I was in my twenties. Love the products will always purchase from now on.

"Even my hairdresser asks what am I doing to my hair as it looks so healthy. I have recommended to many of my friends and they will now see the unbelievable difference in just a few weeks."

Another satisfied shopper remarked: "I noticed the difference after the first use. My hair looked noticeably thicker. Even other people noticed. I have since purchased more and will continue using it. I am really pleased with it and recommend it to anyone with fine hair."

Someone else added how incorporating the shampoo into their daily routine had proved truly life-changing. They said: "The Density range has been an absolute game changer for me. I lost a considerable amount of hair a few months after a serious bout of Covid - it was shocking and depressing. Over the past year I have used this range consistently with seriously impressive results. Thank you!"

Although one user had mixed reports and shared how the shampoo is 'hard to lather'. Although they added: "Really worth the effort when used with the conditioner as hair appears and feels thicker and more voluminous."

Not every review was quite so glowing, however, with one dissatisfied customer stating how the set made their hair 'greasy'. They said: "So far, I am not convinced it helps. Shampoo makes my hair greasy and lank."

On the whole, though, the shampoo has proved a popular choice, with one hair care buff remarking: "The Density Thickening Shampoo and Conditioner already seem to be working on my thinning, shedding hair. The scalp is less visible, and the hair looks healthy. I am delighted."
