All Systems Grow

There’s a sinking feeling when you look in the mirror and notice your hair no longer looks as full as it used to. Maybe it seems flatter, or less lustrous when you style it. Or you’re washing the hair in the shower and noticing more hair falling away than usual. Or your pony tail feels thinner - and your hair’s lacking in oomph, even when you’ve blow-dried it. 

Our LED cap All Systems Grow H-Wave LED Hair & Scalp Treatment - which is just back in - takes clinic-level light therapy and hides it inside an entirely unsuspecting, chic cotton baseball cap. Inside, 125 LED lights deliver a 655nm red light therapy treatment directly to your hair and scalp.

It’s clinically proven* to deliver thicker, fuller, healthier-looking hair. It’s a chic cotton baseball cap under which is concealed 125 LED lights to help reduce excess shedding and support thicker, fuller-looking hair.

The same technology elsewhere could cost you £450. As a member of BEAUTY PIE? It's £199. 

To celebrate its return, right now when you order All Systems Grow, you can choose a gift on us, with your choice of two advanced scalp-supporting serums: just add either the Renewed Density Anti-Hair Loss Treatment for fine & thinning hair, or Youthbomb 360 Hair Restore Scalp Serum to your basket.

Renewed Density is loaded with 3% RedensylTM Complex - the best ingredient for thinning hair - and Yerba Santa Bioflavonoids, which help reduce oxidative stress-induced hair loss. Plus Vitamin PP, Zinc and Arginine to support a super-healthy scalp. Use it as an intense daily treatment or for weekly maintenance. 

If your hair is greying, you could go for the Youthbomb – it’s a leave-in serum spray with Caffeine and Anagain™ to reenergize roots, plus a breakthrough GreyGuard™ Technology helps reduce the appearance of greys. 

Use All Systems Grow for just 10 minutes a day – while you’re walking the dog, or nipping to the shops, or watching TV - for visible redensifying results*. You can remove the LED section to wash the baseball cap, then simply slide it back in. And tackle thinning hair head on.
