#HonestReviewIt leaves a wet, slightly hardened finish, so it doesn't come with an after-bath treatment at night. It's for morning use. The scent is amazing. --Previous review (↓)---It has a thin, oil-like texture. It has a lovely green floral musk scent with a hint of citrus. It leaves hair feeling not sticky, with just the right amount of wetness and less dryness. Some wet products tend to make strands stick together (which is disastrous for those with thinning hair, as it makes the little hair you have look even thinner), but this never happened, and I'm especially pleased with the less dryness it leaves. When I styled it with a hair dryer, it also reduced frizz. When I used it at night, it stayed smooth the next morning. When I used it in the morning, it stayed smooth all day. When I touched my hair, it felt so smooth. It felt so good I wanted to touch it all day lol
Maybe it's because of age, but the frizz around my face has been getting worse, and with the rainy season upon us, I've been struggling with it. I used to get my hair curled, but I hated the loss of volume, so I tried various oils and shampoos to see if that would help, but I wondered if a styling product would be effective, and I came across this product. If I use too much, it makes my hair feel wet, so I'm still not good at controlling the amount, but it's the most effective product I've used so far. I don't use a flat iron, but if I do, I'm sure it will straighten my hair.
This is so good!! Seriously good!! I was stressed out by the excessive frizz in my hair, probably due to age, so I bought this along with Stephen Knoll's Form Control shampoo. Just changing my shampoo significantly reduced the frizz, but using this before blow-drying makes my hair even smoother and more manageable. I've tried similar products from other brands, and while they did make my hair straight, they ended up making it greasy, but this doesn't do that. I'm so glad I bought it because it really does give me beautifully straight hair!! I'll definitely buy it again!
When I applied this product to the roots of my hair, it reduced the volume and made it quite straight after blow-drying. However, it's best to shake it well before use. I accidentally used it without shaking it, and it didn't work as well.
I have curly hair, but I bleached it and couldn't straighten it, so I bought this product. It's gotten so wavy and frizzy with the summer coming around, and I've been worried about it getting frizzy. I've tried a lot of different hair oils and styling products, but this is the best so far. It requires you to shake the two-layer oil before applying, so it's not a push-type product, and you have to open the lid and pour it out, which is a bit of a pain. Even when I used a straightening iron in the morning, my hair would get frizzy and frizzy due to sweat and humidity, but on the days I used this oil, the frizz and frizz were less than usual. If you have very curly hair or sweat a lot, it won't stay completely straight forever, but it has really reduced my stress. I'll definitely repurchase it when I run out!
