"The Finishing Serum serves as the ultimate protector, guarding against heat damage, UV rays, color fading, and humidity. It is exceptional when heat activated. It transforms thin, fine hair, making it look and feel organically thicker. And works equally as well to calm down thick, coarse hair."

Both are serums that protect the hair against heated tools and have UV filters to protect against color fade and humidity without ever weighing the hair down. The Finishing Serum delivers a lighter silky effect, excellent if blow dried into fine, thin hair as it will make the hair feel and look thicker. The Curl Revive delivers a weightier, cashmere effect to the hair so is ideal for all curl, wave and textured hair. It also works very well for thick, coarse Indian, Asian and chemically straightened hair. One can also cocktail these serums. For example, someone with extensions would use the Finishing Serum on the their thin, fine, natural hair and the Curl Revive on their extensions.
The Finishing Serum can be used on both wet hair before drying, and on dry hair too to tame down any frizz. It is exceptional when heat activated, e.g. when blow-dried into the hair. It works like magic, making thin hair feel thicker, and thicker hair feel less bulky. Please be sure to cover each part of the hair.

    Use on damp and dry hair

    The best product ever. I apply to damp hair and before blow drying or air drying, and to my dry ends before brushing. I also like to coat my hair in it before going into the ocean. I started using this product along with the shampoo and conditioner in 2020 and have not deviated since.

    Best hair serum I have tried to date

    I am always on the lookout for products to use for my fine, thin, damaged hair . It’s such a struggle to find products that work and moisturize without weighing down the hair. This works like a charm. I just discovered this brand and I am over the moon. The products work and smell like the best smell you will ever get your nose on. So that’s a win win in my book. The serum is creamy but kinda gel like in a sense . It absorbs into the hair without leaving a sticky or greasy residue. It plumps up my fine hair but keeps it soft and hydrated and not weighed down. I will be investing in the bigger sizes going forward!!! Oh and I need to mention that the Customer Service is top notch!!!!

    Amazing find!

    I consider myself a product junkie and feel like I am usually on top of all the best hair products out there. In the last few years it has been very important to me to find more natural products with out silicones. During my most recent cut my stylist used this serum on my very thick corse hair. Of course I walked out of there with my hair looking amazing, but I thought it was just a salon fluke and didnt feel comfortable paying the price, so she gave me a few samples to try at home before purchasing. Well, that sold me! After getting to play around with it myself for a few washes, I was back at the salon 2 weeks later and purchased the full sized bottle. It literally replaces all of my other hair products and you dont need a lot, so for me, the price is well justified. My stylist told me to use a dime size amount on my hair BEFORE towel drying and it worked like a charm! I truly didnt think that would be enough to cover my hair but it worked so well and my hair felt amazing. The bottle is going to last me quite awhile. I generally go to bed with a wet head, and then throw some waves in it in the morning. My hair looked so full even when I woke up, my natural waves were full of body, and the waves I put in with a curling iron held perfectly for days before I washed it again. 10/10 reccomend, best hair product I think ive ever used!
