Signature collection
There's no better way to protect ALL HAIR TYPES from environmental assaults than with my signature FINISHING SERUM. Hand-picked, custom blended ingredients including vitamins, nut oils, silk, and ceramide, feed hair with nothing but goodness without ever weighing it down. This paraben free formula creates a screen against UV rays, humidity and free radicals: strengthening hair + helping repair split ends + preventing color fade. Lightly scented with white flowers.

The Iles Formula Finishing Serum is a great favorite of freelance hairdressers on a professional photo or film shoot. It's where most of our huge celebrity following first experienced Iles Formula.

This formula has the power to transform dry, brittle hair to sumptuous silk just by blow drying it in to wet hair. It has heat protection, UV and humidity protection, all without ever weighing the hair down. It delivers a memory to the hair that changes form as you ask of it, and lastly it delivers the most expensive looking lustrous shine.

The Iles formula Finishing serum can be applied to both wet and dry hair. Ideally use after using Iles Formula Shampoo and conditioner. Apply small amount to each section on wet hair as blow drying. This will make thin hair feel thicker and calms thick coarse hair. Apply small amount daily to dry hair to protect against heated tools, UV damage, color fade and humidity.

    Unbelievable product! This has completely changed my hair and I will never live without it. The entire line is amazing and worth every penny! I promise you will not be disappointed!

    I love the result. It makes my highlighted hair look naturally smooth even on rainy days but I still give it only 4 stars because the smell is too harsh.
    The first time I applied the suggested amount and my throat was swollen by the strong synthetic-like smell of it. I wonder what plant from the list of ingredients has such strong smell? Anyway, next time I used only a pea-size amount and didn’t have any allergic reaction. So, be cautious and start with a small size.

    Most amazing finishing serum that I have used! It is so lightweight and smooths my hair perfectly and no weighing it down! I wish sephora still sold this, it is my absolute favorite serum that I’ve tried!

  5. Creme De La Jolla Review

    First of all I would like to say excellent blog! I had a quick question that I’d
    like to ask if you don’t mind. I was interested to know how you center yourself and clear your thoughts before writing.
    I’ve had difficulty clearing my mind in getting my thoughts out.

    I truly do enjoy writing however it just seems like the first 10
    to 15 minutes are generally lost just trying to figure out how to begin. Any ideas or hints?

    Thank you! http://wikidoner.com/index.php?title=What_You_Are_Required_To_Learn_About_Your_Skin

    Love, love, love everything about the serum. My hair is fine but I have lots of it; it is curly, when it decides to be, but always frizzy and mad -not, however, with the serum. Using the serum after shampooing and conditioning (Iles Formula), makes my hair behave (‘hair-identity’ transformation) without straighteners/hair dryers or any other product. AND I adore the fragrance – what is it???

    PIA: Ein Jahr im Test
    Das Serum ist für mich das Beste seiner Art. Es pflegt und hinterlässt tatsächlich dieses seidige Haargefühl. Soweit ich weiß handelt es sich hierbei um “gute” sprich auswaschbare Silikone. Es ist ergiebig, nicht aufdringlich vom Geruch her und beschwert überhaupt nicht.
    Nachkaufprodukt trotz Preis.
    Auch Shampoo und Conditioner sind absolut empfehlenswert und hielten trotz nahezu täglicher Benutzung und langen Haaren fast ein Jahr.

    PIA: Testing for a year now
    The Serum is the best of its kind. It nourishes and leaves that silky hair feeling. As far as I know the silicones in it are the good kind, they can be rinsed out. It is rich, has a lovely smell and does not weigh down at all.
    I will rebuy despite the price.
    I also absolutely recommend the shampoo and the conditioner, the products lasted for almost a year despite my daily use/ long hair.

    Love at first feel
    My hair is fine, well past my shoulders, and I have an oily scalp. I squirt a dime sized, or smaller, amount into my palm and rub my hands together. I apply it from mid-length to the ends while my hair is damp. My hair feels luxuriously soft after blow drying and my ends look almost freshly cut.

    Great
    I have tried thus product in a number of ways. I have tight curls naturally curly hair. I used this when my hair was longer on top of mousse and gel and it gave an amazingly smooth and frizz free finish. The smell is fresh and clean and does stay in your hair. I find it pleasant. I have also used this after cutting my hair shorter, straight up after wash with no other products. It still provides a smooth and mostly frizz free finish. The best results have been as a last product over my gel. But it’s always smooth and shiny and far less (almost no) frizz. I live in a humid climate also.

    In LOVE!
    I got this as a sample. I have only been able to get 2 uses out of it since I have very long hair. I honestly really like how my hair feels after using it and the smell. My hair is colored as ombre from brown to blonde on the tips, so hydrating my blonde hair is a major priority and since i have very fine hair, that knots easily, I’m open to trying hydrating leave-ins. When I tried this sample, I pretty much fell in love with this serum, my fine hair is very soft and hydrated and the blonde doesn’t feel remotely bleached. The reason I’m giving 4 stars though is because I didn’t feel like it was helpful with detangling, but I also didn’t have enough to test it.
