For many, the new year signals a 'new you' - and a 'new you' can often mean taking better care of yourself, whether it be your hair, skin or more.
And for those looking to take better care of their hair, the Hair Gain Shampoo and Conditioner Starter Kit is a great place to get that journey started.
This clinically tested, trichologist-approved hair care duo utilises the power of peptides to strengthen the internal structure of each hair strand, making it more resilient and resistant to damage.
It's also formulated with Vitamin B Complex, which nourishes the hair strands from root to top, reinforcing the hair's strength, and rejuvenating shine and vitality.
There is also marshmallow root - an ingredient that soothes the scalp, and seals in moisture for ultra-long-lasting hydration and softness, making it perfect for those who deal with a dry or flaky scalp.
To make a great deal even better, this shampoo and conditioner set leaves your hair feeling clean, fresh and hydrated for up to three days after washing, meaning you'll end up product, extending the life of your products.
The best thing? The formula is completely vegan, halal-certified, making it suitable for everyone, no matter their personal preferences.
It's also dermatologically tested and free from parabens, silicones and sulphates, so it's safe for all hair types, including sensitive scalps and coloured and heat-damaged hair.
And now, at 35 per cent off when applying code BOX35 until 2 January, you can save more of your hard-earned money for yourself, and get your hair revitalised for less.
An Independent Brushing Test in September 2025 found that there was a 64 per cent reduction in hair fall and breakage from the first use, and that hair was less likely to shed on the brush.
And it's clear from reviews that testers are loving the Hydrating Shampoo and Conditioner duo.
One thrilled customer enthused, "By far the best products I have used in a very long time. My curls are soft, bouncy and defined and last longer between washes."
'Out of all the products I have tried, this is genuinely the best; my scalp is also less dry and itchy; I visibly have no dandruff which I have struggled with', another said.
A third added,'I honestly love these products just for the fact that they are actually helping repair my hair in a way no other products have been able to do.'

Hair Gain Scalp Foam
Hair Gain recommends using a foam to prevent hair loss instead of oils and serums, as they can clog scalp follicles and actually delay hair growth.
