If you feel like your hair's been getting finer lately, you're in the majority. Up to 80% of men and around 50% of women experience noticeable hair thinning at some point*. It's a normal biological shift, even if your shower drain is starting to take it a bit too seriously...

Before you look for a miracle cure, let's talk about the high-performance data behind an ingredient that might already be sitting on your kitchen counter: Caffeine.

What does Caffeine do?

• Stimulates hair follicles: Caffeine has been proven to support cell activity within the hair matrix, helping follicles maintain normal function.

• Counteracts DHT: Dihydrotestosterone (DHT) is the hormone responsible for shrinking hair follicles in men with androgenetic alopecia. Caffeine has been shown to help inhibit the effects of DHT, giving hair follicles room to breathe.

• Supports circulation: Improved circulation to the scalp can help deliver oxygen and nutrients to follicles, which are essential for healthy hair growth. 

• Extends the growth phase: Caffeine may help prolong the anagen (active growth) phase of the hair cycle, allowing hair to grow for longer before shedding.

How to get the best results from Caffeine

• 3-minute rule: Leave your Caffeine-infused THIX shampoo and conditioner to sit on the hair for 3 minutes before rinsing to give the ingredients time to take effect.

• Be consistent: To keep the follicles energised, use Caffeine on the hair and scalp daily.

• Combine with other proven ingredients: We don't use Caffeine in isolation; we combine it with Niacinamide, Panthenol, Pyridoxine, Vitamin C and Vitamin E, which work together to support healthy, fuller-looking hair.

Caffeine isn't a quick fix; it's a strategic long-term investment. THIX haircare makes it easy for anyone looking to protect their current density and reinforce existing strands.
