Awesome for eyebrows

I use this on my eyebrows at night, and I have noticed a positive difference in their overall thickness! I put a few drops in the scalp oil that I make as well, and it seems to work really great in that as well. This is definitely a very high-quality product and I feel like the size bottle you get for the money is pretty solid, considering you only need a small amount, as it is pretty thick. The scent isn't too strong, which I prefer, and it does seem suitable for sensitive skin. It is extremely moisturizing, and I would say it is suitable for all ages. The packaging is decent, but I would prefer if it had a dropper on it instead of a regular cap. If you decide to use this on your hair, it is very strengthening, so if you have protein-sensitive hair, you want to be a bit careful with how much you use and what you pair it with! Using extra dark Jamaican black castor oil is very beneficial and is composed of many nutrients really awesome for the skin and hair. 10/10 Reccomend.

After incorporating Sunny Isle Extra Dark Jamaican Black Castor Oil into my hair care routine for several weeks, I noticed a significant improvement in hair strength and a reduction in breakage. The thickness of the oil required some adjustment, but diluting it with coconut oil made the application process smoother. The natural scent was initially strong, but adding a few drops of lavender essential oil made it more pleasant.

Great product

I used to use okay brand castor oil but recently discovered they changed the formulas. That's why I switch to this brand. Sunny Isle is more economical and more pure than Okay. I use it on my scalp as well as skin, brows and lashes. I find out my brows and lashes fall less, and so does my hair. Someone complain about the scent but i m ok with it. It doesn't bother at all. I mean that's what natural ingredients smell like, right? I will continue to purchase this product. By the way, no matter what products u use, massage ur scalp often. It helps hair grow tremendously.

Great

I decided to try this based on the reviews, and I’m so glad I did. The quality is excellent, and it feels nice to use. I’ve been using it for a little while now and really like the results. It was also a great price compared to local stores. The order arrived quickly and was well-packaged. I will be repurchasing for sure. Thanks, iHerb!

100% Pure

This extra dark Jamaican black caster oil, is my favourite castor oil. Its 100% pure quality. You can use a small amount of it on your scalp and hair for a healthy daily treatment or warm and apply at night for a deep hair moisturize conditioner (before washing) and a eyebrow and eyelash thickener. the scent is mild and it comes in a glass bottle.
