I invested in the 1 litre set of the UV shampoo & conditioner along with the 500ml Lifesaver treatment. This is after I tried out the travel-sized equivalents way back in 2021. I bounced around a few other products since then, but have come back to these - they're simply the best on the market. I believe this is because the products are silicone-free and do genuinely rebuild the hair with continued use. I've taken the plunge and gone silicone-free and my hair is in such great condition already. Though the initial outlay might be considered "pricey" - a little does go a long way and it's leaving no nasties in your hair, so it's actually very reasonably priced. I'm a convert for life.
The 1ltr bottles of shampoo and conditioner last me around last me around 8 months and using the lifesaver once a week means I get the best of both worlds - great hair and a reasonable price given how long it lasts. Volumising cashmere is my go to to keep life in my hair between washes. Love it. Wouldn’t be without it!
