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!

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.

Originally posted on Philip Kingsley
Elasticizer has become an essential staple in my self-care routine. I have fine, postmenopausal here but have been using it for years because I’m addicted to the enhanced, healthy bouncy texture, revived colour and shine. My hairdresser always comments about the excellent condition of my highlighted hair, too.

My daughter introduced me to the brand and this product recently at 60 my hair is shiner than it has been for ages no frizz or dryness . Long lasting and definitely worth combining it with the rest of the range

Amazing product. After only three
Originally posted on Philip Kingsley
Amazing product. After only three weeks of use (three applications) I can already notice my hair is less fragile, has more bounce and doesn't feel as dry and dehydrated. I did not believe it was possible for a product to have such an impact. I leave it overnight and it has not made my hair feel weighted down or extra greasy. I also believe it has resulted in less hair loss.
