It has a nice scent! Even though it's an oil, it's not heavy and leaves my hair feeling smooth. I wonder if it won't frizz on rainy days? Well, it does. It's quite curly. But I keep buying it because I love the soothing scent.
It has a soothing citrus scent, and it makes my hair easier to manage, so it's easier to style.
I love using nail oil, so I decided to try the hair oil as well. I'm in my 40s and suffer from frizzy, dry, and damaged ends, so after a bath, I apply this and blow dry my hair. After it dries, I apply it again, focusing on the ends, and then go to bed. The next morning, my hair is perfectly set. It's so good that I no longer need to use a straightening iron every morning! I hope this product never goes away! It's even more popular than the nail oil!
This oil is very light and doesn't feel sticky even when used in large amounts. It's not particularly moisturizing, so I use it in combination with other hair products, and I find its lightness makes it easy to use. My hair gets frizzy and curly even with a little humidity, so it only helps with taming frizz on rainy days, but I think it'll be effective for those with less frizzy hair. The scent is refreshing, with notes of mint and citrus, and barely lingers, which I like. I sometimes notice a slight oxidized smell of oil in the evening, but it's tolerable. P.S. I always use Orbis Hair Milk after washing my hair, and I use the oil as a styling product after drying. Applying about 1.5 pumps of this product after the hair milk and letting it dry significantly reduces frizz, leaving my hair fluffy and smooth. I also use another 1.5 pumps on the ends and around my face, where frizz tends to be more pronounced. It seems like a product that needs to be used wet to keep frizz under control.
It's great that you can take care of your hair while enjoying the soothing scent! I hope my hair improves with continued use.
