Birchbox Breakdown

Good haircare doesn’t stop once you hop out of the shower. Serum might be overlooked, but it’s essential for hair health—especially if you use heated tools or, really, plan to go outdoors at all. This formula, created by celebrity hairstylist Wendy Iles, is the final step and only styler needed to achieve the "spun silk" look when using the 1-2-3 Iles Formula regimen. The rich blend of macadamia nut oil, argan oil, and tucuma seed butter nourishes hair, protects it from drying UV rays and frizz-causing humidity, and helps seal split ends. Bad hair days, meet your match.

How to Use

Following using Iles Formula's Haute Performance Shampoo and Conditioner, comb a small amount of serum through damp or dry hair, focusing on the mid-lengths to ends. Air dry or blow dry and reapply throughout the day as needed.

Wonderful

I used the shampoo, conditioner and serum samples from my birchbox. I use a blow dryer on my fine hair so it becomes very dry. After these products my hair was shined and felt healthy again. Only had to use a pea size of the serum, so a little goes a long way. I'm going to purchase the serum. Love this product!

Time to switch!!!

I was so stuck in my old ways and afraid to try new things so here this sat and I decided to give it a shot. WOW, the scent alone was amazing and my hair woke up and finally behaved like I wanted it to lol!!! I'm actually here to order now, sure wish I'd of opened the sample sooner bc it's really everything and more. My hair is fine but I have alot and it has 10 different curl types going on plus it's dry towards the ends, it's also one length to my butt! This is my NEW GO TO I LOVE MY HAIR PRODUCT!!!Price is worth it♡

Loved it

Felt really great in my hair, didn't weigh it down or feel greasy. Loved my hair when I woke up the next morning. I usually have very frizzy hair and this definitely helped! Will be purchasing.

Soft curls

I absolute loved how this left my usually straight and fine hair with soft beach waves. Most products I use leave that "crispy" feel and look. This finishing cream left my hair with just the right amount of wave and it smells great. I've never spent this much money on a hair product before,but I will be purchasing this one!
