Great toner
My hair tends to get a brassy color in the sun and this toner makes it look more natural. Only downfall was I should have worn gloves, my finger nails were all purple stained.

Olaplex No 4 purple shampoo
USE WITH EXTREME CARE. CONSULT PROFESSIONAL ADVICE IF THIS PRODUCT IS WHAT YOU TRULY NEED FOR YOUR HAIR TYPE. I had a few areas which got the brassy gold color when I frosted my hair. I looked online for advice on how to correct this and the one video I watched showed putting the purple shampoo directly on on your entire hair, (WET HAIR FIRST WITH WATER) combing it through & leave on for 5 minutes. They didn’t wear gloves, BIG MISTAKE! This purple shampoo stains your skin, PLEASE wear gloves! I did as the video said… unfortunately my frosted blonde Pkd up the purple & it stained my frosted hair!!! NEW problem!! I had to watch an additional video on how to correct the purple staining from the shampoo! My poor hair went through a lot of processing. I had to bleach over the purple which I mixed powder blue bleach , developer & a shampoo mixture.. it worked!!! Now I have to buy product to recover my hair from all this product distress I put my hair through. Sometimes it’s better to just go to the salon and let the professionals do it:)
