Hair loss and balding can cause a lot of hassle and heartache for men and women alike. When hair starts to thin, it can often feel like nothing can be done save for trying expensive treatments, but this product from Boots is being hailed as ‘really great at concealing bald spots’.

The Nanogen Hair Thickening Keratin Fibres cost £24 for a two-month supply, down £6 from the orignal price of £30. The clever product works by the user shaking some fibres evenly over the thinning area before blending them into place with the fingertips, and when matched with the user’s natural hair colour they are said to blend seamlessly and make hair look fuller.

The fibres are made of 100% natural keratin, which is a fibrous protein found in hair strands. Available in 10 different shades, the fibres can be used on their own or mixed with another colour to mimic highlights.

If this product isn’t calling out to shoppers, they could try the Watermans Hair Fibres Hair Loss Concealer for £15 from Superdrug. These work in a similar way to the Nanogen product, and helps to conceal bald spots and disguise thinning hair.

Alternatively, Boots has the Toppik Hair Building Fibres Powder for £22.95, which uses keratin fibres made from natural wool sources and is said to be able to withstand sweat, rain and wind. This one is only available in three shades on boots.com, so there’s less choice than with the Nanogen version.

The Nanogen fibres also have plenty of fans at Boots. One buyer said: “Definitely would recommend this product, it’s excellent. So easy to use and has given back my confidence.”

Another said: “Really good and covers everything up really well. Lasts long.”

A third shopper added: “Best hair coverage I have ever bought. Worth every penny.”

However, one shopper noted: “Really great at concealing bald spots. Have been using it for years which is why I think the high price is a tad too much. Overall it has really restored my confidence. Try this if you see some thinning on your crown and can also help a receding hairline. Just don’t put too much on or it will get noticed.”

Another said they struggled to get a perfect match to their hair colour. They wrote as part of a longer review: “I like this Nanogen Black hair fibres but they are not truly black but grey.”
