Want thicker hair for longer? Introducing THIX caffeine hair routine

Start your day drinking lemon and hot water? Eat five a day? Add spirulina to your smoothie? Take a ginger shot for the sniffles? We know that daily supplements and superfoods can improve overall health and energy levels, so why not demand the same quality when it comes to ingredients in our hair care?

Enter THIX: The Functional Hair Care Routine

THIX is designed to make weak hair strong and protect what you’ve got. A protein-strong, vitamin-rich, caffeine boost for your hair, it is proudly silicone-free, ethanol-free, sulphate-free, GMO-free, vegan-approved and uses scientifically proven ingredients.

80% of men and 40% of women will experience some level of hair loss in their lifetime—and not just in old age. 25% of men will experience it before the age of 30. Hair loss can be progressive or temporary, depending on the cause.*

When it comes to holding on to the hair on our heads, once it’s gone, it’s much harder to grow it back. This means that the best prevention occurs when we’ve still got a full head of healthy hair. However, often we don’t take action until we notice the first signs of thinning or breakage.

Developed by London-based venture studio Otherway, in partnership with a team of former Boots innovation experts, THIX is specifically designed to stimulate, strengthen, repair and thicken the look and feel of the hair. Backed by science, not magic.

How THIX Works

THIX applies functional knowledge of nutrients to hair care, using a high-performance combination of caffeine, essential proteins and vitamins in the purest, simplest forms. The gender-neutral range consists of a deep-cleansing shampoo, a nourishing conditioner and a unique styling paste to thicken and protect. Sold exclusively at thixhair.com.

THIX Banishes Single-Use Plastic

Sustainability comes as standard at THIX. Bathrooms generate a lot of plastic waste and clutter, with over 8 million tonnes of plastic ending up in the oceans each year. THIX uses 100% recycled aluminium bottles, caps and lids. Aluminium is widely recycled, infinitely recyclable and never deteriorates, making it the most sustainable material for personal care products.

Nearly 75% of all aluminium ever produced is still in circulation today, and because it’s recycled, it uses 95% less energy than virgin aluminium. The optional plastic pump is recommended for the conditioner and can be reused with each new bottle.

Caffeine-Based Formula

Caffeine is a scientifically proven, natural stimulator of hair follicle growth. Studies of human hair follicles show that caffeine increases cell energy by acting against a protein called phosphodiesterase. The research shows that caffeine combats hair loss by inducing hair cells to produce Adenosine Triphosphate (ATP), a molecule that carries energy to help stimulate growth. Caffeine has also been shown to increase the protein insulin-like growth factor (IGF-1), an important signalling molecule in promoting hair growth. More specifically, caffeine has also been shown to potentially reverse the effects of dihydrotestosterone (DHT)—the main hormone involved in common balding.

Protein Strong

Our hair uses proteins to build tissue cells. Natural proteins re-energise hair roots and increase the structural strength of hair follicles, making hair healthier, thicker and stronger. Keratin is the dominant protein in hair, making up around 90% of the composition. It is scientifically proven to generate hair growth and regeneration. Not only does the THIX formula include natural plant keratin (derived from corn, soybeans and wheat), but also the vitamin biotin (B7), which stimulates more keratin production and can increase the rate of follicle growth.

Vitamin Rich

Healthy hair needs nutrients to help cells thrive. The THIX formula incorporates a multitude of vitamins to repair broken follicles and make new hair feel thicker and stronger:

  • B3 Niacinamide—improves blood circulation to the scalp
  • B5 Panthenol—maintains moisture in the hair
  • B6 Pyridoxine—supports healthy hair growth and revitalisation
  • Vitamin C—promotes hair health, helps reduce hair loss and prevents dry hair and split ends
  • Vitamin E—increases capillary circulation in the scalp to promote hair growth

Fresh & Clean Fragrance

Not just an amazing aroma, mint and eucalyptus also work to energise the scalp and strands, leaving your hair as good as new. Mint cleanses without stripping away the hair’s natural, essential oils or colour. Both botanicals invigorate and purify the skin and scalp.

The THIX Master Trio: A Complete Routine for Thicker, Healthier Hair

The best way to use THIX is as a complete, daily hair care routine with the master trio: caffeine shampoo, caffeine conditioner and the unique caffeine leave-in styling paste.

The master trio deep cleans, nourishes, conditions and repairs the hair, while the leave-in paste allows more nutrients to be absorbed throughout the day. THIX is protective and long-lasting, with all ingredients supporting healthy hair.

For best results, use daily for three months, though some users notice a difference straightaway. Unlike stronger hair loss products, pausing THIX won’t cause hair loss. Using products individually still brings benefits.
