PEPTIDE PREP™ pH maintenance shampoo

I have been a customer from the very beginning and use all 4 products almost exclusively. I was advised to use the Maintenance shampoo regularly, Detox monthly and Serum 4x post hair coloring. I also use the oil but have a little trouble with the distribution of the oil because it has a water like consistency. I have loved the shampoo and serum, even buying it for my adult daughter because of the great results.

Just recently, I have had to reintroduce conditioner after not using conditioner very infrequently due to brittle hair. I also have installed a hard water filter to avoid the poor hair/skin issues. Is there a sweet spot you can recommend for using conditioner in conjunction with the full line?

I have everything you guys make and I absolutely love it if I don’t want to blow dry my hair I don’t have to it’s almost like a keratin treatment too!!

I have very long hair past my waist. I’ve had scalp buildup problems in the past and my hair has felt really heavy and unmanageable at times. I reluctantly (because of the price) tried k18 and I’ve been really impressed. My hair feels light and clean, it’s more manageable and I can go longer in between washes now without having to put my hair in a bun. I don’t even use conditioner, just the shampoo and the leave in once I’m out of the shower. The price is steep but considering you use so little and it’s so effective I say it’s absolutely a good investment and it’s worth it. The sample sized shampoo lasted me 6 months, Im sure the large bottle will last me an entire year or more. I’d say if you’re worried about the price just go for it you’ll save money in the long run and have beautiful hair.

My dry, course, damaged hair is being transformed with these k18 products! Worth it!

Love all the K18 products. This says I could use this shampoo every day if needed. I’ve only used it a few times at 2-3 days in between however it’s always good to have options.
