WENDY SAYS

"The Finishing Serum serves as the ultimate protector, guarding against heat damage, UV rays, color fading, and humidity. It is exceptional when heat activated. It transforms thin, fine hair, making it look and feel organically thicker. And works equally as well to calm down thick, coarse hair."
FAQS

What's the difference between the Finishing Serum and Curl Revive?
Both are serums that protect the hair against heated tools and have UV filters to protect against color fade and humidity without ever weighing the hair down. The Finishing Serum delivers a lighter silky effect, excellent if blow dried into fine, thin hair as it will make the hair feel and look thicker. The Curl Revive delivers a weightier, cashmere effect to the hair so is ideal for all curl, wave and textured hair. It also works very well for thick, coarse Indian, Asian and chemically straightened hair. One can also cocktail these serums. For example, someone with extensions would use the Finishing Serum on the their thin, fine, natural hair and the Curl Revive on their extensions.

How is it best to use the Finishing Serum?
The Finishing Serum can be used on both wet hair before drying, and on dry hair too to tame down any frizz. It is exceptional when heat activated, e.g. when blow-dried into the hair. It works like magic, making thin hair feel thicker, and thicker hair feel less bulky. Please be sure to cover each part of the hair.

Can I combine Iles Formula with other styling tools?
les Formula is most effective when used without other styling products like mousse or hairspray, as they may diminish the lustrous, sumptuous results our formulas provide. However, you can continue to use your regular styling tools. Our Finishing Serum offers built-in heat protection for all styling tools, ensuring your hair remains protected and styled to perfection.

It's performance is to nurture and strengthen hair and scalp without leaving any residue behind so it's perfect for even the finest of hair.

Is the Finishing Serum safe for color treated or bleached hair?
Yes, our formulas were born to nurture and repair all types of hair. The more damage to the hair, the more phenomenal the performance of the formulas. The root extract in our Shampoo buffs over damaged porosity bars on the hair shaft which are particularly common in colored hair. The Conditioner is essential in repairing any damage as it locks the outer hair shaft and instantly detangles hair.

    Frizz buster

    I’ve been fighting frizz forever. This serum leaves my hair smooth and shiny without having to rely on my flat iron which I’m sure is not good for my hair. Love it!

    Best Hair Product Purchased in a Long Time

    I have baby fine grey hair and no body whatsoever. That is until I purchased Iles Finishing Serum. Now my hair feels a bit thicker and it behaves well. Glad I took the subscription because now I won’t do without.

    Amazing product 🙏

    I discovered this product about 6-7 years ago and I have been obsessed with it ever since. I have fine hair and it doesn’t weigh my hair down, and leaves it frizz free and very soft. This product is literally sooooo good! If you have fine, soft, straight hair like me, it’s perfect because it won’t weigh it down or make it greasy!!
