Key Benefits
Full Control Anti-Thinning Scalp Serum is a lightweight treatment created to help protect the scalp from water damage and mineral buildup while supporting stronger-looking hair from the root. Designed for daily use, it helps reduce shedding over time and promotes a healthier scalp environment.
Klean Complex™ works to counteract mineral buildup and support balanced scalp pH, while improved hydration helps calm visible signs of inflammation and rebalance the scalp microbiome. The fast-absorbing formula penetrates effectively during the post-wash window, helping protect the scalp for up to 72 hours without leaving residue.
Dual chamber technology keeps key actives separate until first press, helping preserve potency and pH stability for consistent performance. With regular use, hair appears stronger, fuller and better supported at the root.

- Helps counteract mineral buildup.
- Supports balanced scalp pH.
- Lightweight, fast-absorbing formula.

Why Hello Klean is Healf
Full Control Anti-Thinning Scalp Serum uses dual-chamber technology to protect ingredient stability and potency until first use. Rather than combining all actives into a single formula where peptides and antioxidants can degrade or shift outside their optimal pH range, the system keeps the active blend and hydrating base separate to prevent oxidation and instability. Once activated, the formula mixes freshly to deliver maximum performance. It features peptide growth factors to support renewal pathways linked to healthy-looking hair density, 0.4% zinc chloride to enhance peptide delivery and maintain a balanced follicle environment, and 5% green tea extract to provide antioxidant support and calm visible sensitivity. Klean Complex™ works alongside osmolytes such as erythritol, trehalose and betaine to help counteract hard water minerals, support scalp pH balance and reinforce hydration. The formula excludes over 1,600 concerning ingredients, including SLS, SLES, parabens, phthalates and silicones. This advanced system helps you support fuller-looking, healthier hair from the root.

The best wellbeing website…
The best health and wellbeing website in the UK. The range of products is fantastic, even on hard to reach USA products. I love the subscription service too. I'd be lost without this website.
Alex
Amazing!
Healf isn't just another wellbeing brand. They really get it. The products are fantastic, and the support is always so personal and genuine!
Janet
Great products, service, and customer support
Healf have a great range of wellbeing products not available elsewhere in the UK. They are competitively priced as one-off, but even better if you take up the 'subscription' which is super flexible too. I'd have no hesitation in recommending Healf.

I love Healf
It's the only place I get really decent health and wellbeing brands, particularly US brands. I've bought a Pvolve set, lots of Skinny Confidential stuff, Thorne supplements etc., the really great stuff that's impossible to get otherwise.
