With LASIO Keratin Treatments you have options. You can wash your hair the same day right in the salon, at home that evening, the next morning, or anytime within 24 hours of receiving your treatment.

With LASIO Keratin Treatments you can color your hair the same day as your treatment. Having a treatment performed after your color service will help to lock in your color and rehydrate hair.

We highly recommend it!

If color is not performed the same day, or BEFORE a keratin treatment, you must wait two weeks to get a color service. We recommend doing your color first, and then your LASIO Keratin Treatment. But if you forget -- or have roots that need to be covered -- then waiting two weeks after your treatment is perfectly fine.
It is extremely important to use sodium chloride free hair products after receiving a LASIO Keratin Treatment. Because LASIO Keratin Treatments are water-based -- not silicone based -- we require sodium chloride free products, not sulfate free. Salt and chlorine will strip the keratin from your hair. We highly recommend using LASIO's HYPERSILK products.
Yes, LASIO Tropic could be applied on previous chemically-treated hair.

To apply LASIO on a chemical service other than color in one week, a strand test should be performed.
You can email Morisha Gaul (our VP of Education) at and she can work with you directly to get that going.
1. You should use a ceramic flat iron. LASIO offers a 1" ProStraight Ionic Flat Iron for salon pros on our PRO site.
