    I will never be without this!

    Ok, this product is amazing. I’m mixed race and have curly 3b hair that I normally wear straight in the winter and curly (air dry) in the summer because I live in a super humid area and it’s impossible to keep straight in the summer anyway. This is a total game changer.

    I ordered after attending an event in a hotter than expected ballroom in the DC humidity and felt my hair, which was perfect when I left home, expanding by the minute. My bangs were a puffy mess and my hair was twice as large by the end of the night. The following week, this arrived and I tried it and my straight hair withstood a day outside in the humidity and several rainy days under an umbrella. I started getting frizz when I actually got misted on BUT a quick pass with a flat iron had it back to straight and shiny in no time. Previously, any amount of humidity ruined my flat ironed style to the point that I had to rewash and start over.

    I’m also excited to try it on my curly hair to see if it helps with shrinkage. Highly recommend!

    (Only minor order nit is that Amika sent me a coupon code that didn’t work and didn’t include the promised free sample, but otherwise shipping was quick!)
