Brilliant product

Originally posted on Philip Kingsley

Brilliant product. I use it with my regular conditioner and leave for 1-2 minutes then rinse off. My Afro Caribbean relaxed fine hair feels instantly smooth and soft and also styles a lot easier with my hot brush. Results are actually visible after styling.

Originally posted on Philip Kingsley

I’ve been really impressed with the Kingsley Elasticizer Booster. It leaves my hair feeling noticeably softer, smoother and more manageable without weighing it down. It’s especially good for dry or damaged hair, giving it a healthier-looking shine and a little extra bounce. A great addition to my haircare routine!

A regular purchase and I would not be without it. Adds a little extra softness and manageability to my hair on the days I don’t use my Elasticizer extreme treatment.

Love it! Brillant product that adds texture to my fine, thinning hair. As with many of the Philip Kingsley products, you only need a small amount. Another product that will now be a permanent part of my haircare routine.

hair looks smoother and more polished

Originally posted on Philip Kingsley

I’ve been using the Elasticizer Booster Restoring treatment, and it has quickly become one of my go-to hair care products. It gives my hair an instant boost of hydration and helps bring back softness and shine. What stands out most is how it improves the overall strength and elasticity of my hair. It feels more resilient and less prone to breakage after regular use. Despite being a restoring treatment, it still feels lightweight and doesn’t leave my hair feeling heavy. I also noticed that my hair looks smoother and more polished, with less frizz and better manageability throughout the day. The texture of the product is rich but easy to apply, and it rinses out cleanly. Overall, this is a great addition to any hair care routine, especially if your hair needs extra repair and nourishment. I would definitely recommend it.

Less shedding.

Originally posted on Philip Kingsley

I have only used this product once but already there seems to be improvement in my hair. As someone with hypothyroidism I suffer hair loss and after using this there doesn't seem to be so much hair in my hairbrush and the ends seem less fragile. I like that it is recommended for weekly as I am not one for preening my hair on a daily basis. Finger's crossed for even less hair on my brush or clogging up the drain in my shower!

Originally posted on Philip Kingsley

I first got this as a small sample and used it once—I couldn’t believe how soft and silky my hair felt. You don’t need to use much, as a little goes a long way. It also smells lovely and leaves my hair very soft, even in our hard water area. I liked it so much that I bought a big bottle.
