Power

Power is a men's grooming brand focused on hair loss and beard growth. It sells a range of shampoos, supplements, serums, scalp tools and hair-thickening fibers under the tagline "For Greater Hair" [1]. The company positions its products around a single problem — thinning hair, receding hairlines and patchy beards — and frames its purpose as helping men counteract that so, in its words, "every man can look and feel his best" [6].

Little is documented about the company behind the brand. Its website (powerfibers.co.uk) is a sparse catalogue with no about page, founder names, founding year, headquarters or company registration disclosed, so those details are not established here. The brand appears to be British: it operates on a UK domain and is stocked by the men's grooming retailer Gents.co.uk, which lists prices in pounds and ships within the UK [7].

The catalogue splits into two lines, hair and beard [2]. The hair line runs from shampoos and supplements to a scalp-stimulating brush, a micro-needle roller, an activator serum and the hair-building fibers the brand is named for; the beard line mirrors it with growth kits, supplements, oil and rollers.

The signature product is Power Fibers, a hair concealer the company describes as "small cotton fibers that are charged with static electricity, making your hair appear thicker and fuller — in less than a minute" [3]. It is sold in a 25-gram container in five shades and is applied by shaking the fibers over dry hair, then fixed with a spray. At the retailer Gents.co.uk the product carries material and value claims not stated on the brand's own pages — that it is based on organically grown vegetable cotton fibers and contains no parabens [7] — and is marketed as a larger-volume alternative to Toppik, at "twice as big" [7].

Alongside the fibers, Power sells a Greater Hair Growth Kit — a sanitizer, micro-needle roller and activator serum described as "all you need for stronger and thicker hair" [4] — and oral supplements built around Cynatine HNS, a keratin ingredient the brand links to hair-follicle productivity and growth [6]. Retailer listings name further active ingredients across the range, including oleanolic acid, apigenin, Biotinyl-GHK, Procapil and Follicopeptide [6].

Power states that its products "have repeatedly shown to improve and maintain strong hair growth," though no clinical studies or efficacy data appear on its site [2]. Such growth and anti-hair-loss claims are made by the company itself rather than sourced to independent testing. On the retailer side, Power Fibers holds a rating of 4 out of 5 stars across 117 customer reviews at Gents.co.uk [7].

The brand is active. Its website carries a 2026 copyright and a full live catalogue, and its products are stocked and reviewed at Gents.co.uk. Rather than selling directly for checkout, the brand site routes shoppers to that retailer through a "Shop here" page [5].
