The jewel of the ILES FORMULA haircare line is the CONDITIONER. It is the raison d’être for the entire collection. This paraben free formula instantly transforms damaged, straw like hair into sumptuous spun silk perfection. Put to the test on today’s biggest celebrities and on the sets of prestigious directors and photographers - ILES FORMULA repairs and revitalizes even the most damaged hair instantly. Knots and tangles slide away leaving hair beautifully healthy, with a delicate perfume of white flowers. Silk from Japan create an immediate voluptuous effect on the hair. The addition of high technology aids to instantly close down the hair cuticles to create a beautiful smooth surface. Tucuma Palm and the seeds of the Macrobola Tree are sourced from the Amazon rain forest in Brazil, as well as 16 other propriety ingredients including Vitamin E and B5 for total hair rejuvenation.
After using the Iles Formula shampoo apply the Iles Formula conditioner. Apply the conditioner to mid length and ends of the hair, then comb through for even distribution. The comb is the vehicle that will deliver to the roots precisely what is needed. Rinse. Think of this conditioner as nutrition for the hair, a little residue left in the ends of brittle dry hair won’t harm, it will feed the hair with nothing but goodness.

Apply to mid lengths and ends than comb through for even distribution.

Directions For Use

The Conditioner is our jewel and INSTANTLY repairs all hair texture to soft silk. The key is to comb the conditioner through to ensure even distribution. If you don't have a wide tooth comb please use a wet brush to comb the conditioner through your hair. Our conditioner heals hair by closing the hair cuticles tightly without coating it like traditional conditioners, nor leaving harmful residues like protein or keratin. Its performance is phenomenal.

    Simply the best

    I just tried your conditioner for the first time and am blown away by the results. I’m very impressed. I would love to try the finishing serum, but since I have the keratin protein treatment and can’t use sodium chloride or sulphates, I’m staying away from silicones to avoid build-up.
    Also, since I am now a convert since first trying this brand literally 20 minutes ago, I’d love to switch over to your shampoo as well but I’m not sure if the sulphates and sodium chloride it contains would strip my keratin treatment? Are the sulphates the more naturally derived and gentle ones, or not? And is the sodium chloride a trace from the raw materials, or is it added in?

      Thank for reaching out. Iles Formula is sulfate-free, so no worries there also paraben-free! You have absolutely no problem using the entire range of Iles Formula on your keratin treatment. We have many customers with Keratin treatment that swear by Iles Formula as their home care and we have many professional salons that suggest Iles Formula as the absolute home care for their keratin treatments.

      Dear Penelope, Thank you for the review and your good question. Please note the Iles Formula Shampoo is sulfate-free + paraben free + silicon free. You will not find better to nurture your keratin treatment than Iles Formula. We have many keratin treatment clients using our entire range. Do consider the Iles Conditioner too as it is especially phenomenal after all chemical and keratin treatments in delivering the hair shaft back to an immediate healthy state.

    Bewirkt wahre Wunder V. Nieskens
    Nach nur einer Anwendung sah mein Haar gesünder aus und glänzte super schön. Ich kann das Produkt – die ganze Reihe- nur weiterempfehlen.

    Does true miracles. (V. Nieskens)
    After only one application my hair looked healthier and so very shiny. I can highly recommend this product, along with the whole ILES FORMULA series.

    pure magic
    This is the best conditioner I have ever used. Leaves hair feeling like silk. Very lightweight yet incredibly moisturizing. The price tag is worth every penny!

    A little bit of this goes a long way, which is good given the price. Also, it doesn’t smell as overwhelmingly strong as the shampoo (or my olfactory senses are dead by the conditioner stage) so helps tone that down a bit. I bought both together and I think the products will last me a while.

    High quality stuff – makes a difference!
    I have naturally dry, curly hair which I wear straight, but due to all the heat styling and color treatments it’s pretty dry and even more frizzy than it would be naturally. I tried Ouai and was disappointed. So then I shelled out for this, and after just one use I can definitely see a difference. It’s not 100% damage-free of course, but the amount of difference I saw in one use makes me think repeated use will get even better results. Ordered the serum today!

    hands down HG Conditioner
    After tirelessly looking at reviews I stumbled upon this conditioner. I have hyperthyroidism and my hair sheds like crazy but I’ve been using this a month and can tell a huge difference, no more clumps of hair coming out in the shower or when I run my fingers through my hair.
    I don’t care how much this conditioner costs I will gladly pay it for a product this phenomenal.

    Quick Take: doesn’t weigh hair down, rich, strengthening, shiny, soft, managable
    Just one use it gave me soft shiny hair and no frizz or flyaways! I have dry hair and oily scalp so i have to wash my hair every day and this shampoo and conditioner gives me healthy soft hair every time. I received compliments about my hair the 1st time i used it. I’ve tried other products that are sold in sephora and this is by far the best!
