    Leaves my hair so soft

    I use the hair mask once per week after washing with the Growth Shampoo and conditioner. This is the first mask I have been able to use from root to tip without it weighing down my hair. Hair is left soft, shiny and smooth. If you haven’t added the mask to your hair routine, you should.

    Absolutely brilliant product!

    I absolutely love this hair treatment. It’s easy to use and leaves my hair shiny and so soft. It smells devine! I’ve been looking for a product that could help my damaged frizzy hair and I’ve definitely found my hero product. The only issue I have is you really do need a key to get all the product out of the tube which I didn’t realise when purchasing so I think it would help to sell it with a tube key or maybe add a note mentioning this as I will need to order one separately to get all the product out of the tube as I don’t want to waste a bit, I love it!

    Excellent stuff

    I will say that my hair is a ball of stress, I swim, run, and have it coloured. It’s also curly. Not a happy head of hair. However! This stuff worked wonders, no tangles, no dry ends, no dullness!

    My hair is actually shiny and the curls are defined and smooth.

Got questions? Don’t worry, we have the answers

What is G4 Hydra-Gloss Treatment Mask?

G4 Hydra-Gloss Treatment Mask is a 3-minute hydration mask to strengthen, lengthen and moisturise strands for a healthy, mega-watt shine- in minutes. The multi-tasking formula works to restore hair to its prime while supporting natural growth. Formulated with hyaluronic acid, argan oil and shea butter with a biomimetic ceramide to reduce breakage and split ends. G4 is suitable for all hair types, styles and textures - curly, straight, coloured, extensions, damaged, dry and more.

Should I use G4 Mask and G3 Conditioner together?

We recommend using the G4 Hydra-Gloss Treatment Mask directly after cleansing with G2 Strength + Length Shampoo. However, if you have dry or fragile hair, or a hair type that requires more hydration like curly or coily hair, you might enjoy the extra nourishment the G3 Strength + Length Conditoner provides before applying the G4 Mask. The range is customisable to your hair needs.

How do I get the best results from the G4 Hydra-Gloss Treatment Mask?

After cleansing with our G2 Strength + Length Shampoo, evenly distribute the treatment root to tip. Leave on for 3 minutes. Or chill for longer, then rinse. There is no need for conditioner, simply follow with G1 Overnight Boosting Peptide to promote hair growth.

How soon can I expect to see results from G4 Hydra-Gloss Treatment Mask?

After just a single application of G4 Hydra-Gloss Treatment Mask hair will be shinier and feel more hydrated.
