Description
Mielle's Avocado & Tamanu Anti-Frizz Stay Straight Serum smooths and seals the hair's surface to help block humidity and maintain sleek styles. This lightweight formula helps protect against frizz and reversion while adding a natural-looking shine. Infused with avocado oil, known for its intense moisturizing benefits, the serum helps hydrate dry strands for a softer, more manageable feel. Tamanu oil helps to boost shine and promote a polished, flexible finish without weighing hair down.
Ideal for damp or dry hair, this serum supports smoother, straighter styles that stay touchable and frizz-resistant through daily wear.
How to Use: Shake well before use. Apply a dime-sized amount to clean, damp hair and distribute evenly from roots to ends. Blow-dry thoroughly and style as desired. For added shine and smoothness, apply a pea-sized amount after styling.

Helps hair with frizz
[This review was collected as part of a promotion.] This helps with my hair keeping it less frizz and neat. This neat packaged spray bottle does the job when applying the product to your hair. This light spray not only smells great but is worth every penny.

Not bad
[This review was collected as part of a promotion.] I received this product complimentary for my honest review. This is one of the few products in this line that work for my hair. It creates a smooth sleak of finish. It feels hydrated but leans toward the oily side

Great smell!
[This review was collected as part of a promotion.] I received this product for free from influenster and Mielle Avocado and Tamanu in exchange for my honest review. The smell of this sérum is AMAZING, I'm obsessed, my hair looks shinier when I use it, it's a lot of product, this sérum is gonna last a while, it helps with my frizz BUT makes my hair very greasy.

Nice
[This review was collected as part of a promotion.] This product has a very strong scent. It is reminiscent of herbal essence or garnier fructis. I spray this into my hands and work it into my hair so that I have more control over how much product I am using. By doing this, I can prevent it from weighting down my hair. It works nicely for the straight sleek look.

Dispenser needs Improving
I love the content of the bottle. I hate how the product is dispensed. The product is too thick to be sprayed onto the hair. There should be a pump dispenser where you just pump the amount you want into your hand and then apply it to your hair. That’s the only thing wrong with this product. In order for me to use it properly I need to open the bottle take the dispenser out and pour it into my hand. Please make this change.

Does nothing.
It didn’t do anything.

We're sorry if the serum wasn't quite the match for you. It might enhance the results in your routine pairing it with the Avocado & Tamanu Anti-Frizz Slip & Seal Leave-In Conditioner. It can help nourish and moisturize your hair, which might give you better results when used together with the serum. The combination should help with frizz control and keep your hair looking sleek! Let us know if we can empower you further!

This is Exactly what I needed!!
I had to get online to write a review. I’ve permed my hair since elementary school. I finally decided to go natural but love the look of straight hair but no longer want to use the hard and heavy products. This stuff is exactly what I needed! After I wash and blow dry my hair. I take a small section, apply it to the root and flat iron. It stays until the next wash. This line will allow me to be naturall with the sleek look!

Anti frizz stay straight serum
[This review was collected as part of a promotion.] My hair naturally falls flat and I haven’t really had much experience with hair serums so much. I used a super teeny amount and the serum seemed to help tame some of the weird flopping my straight hair does at times without appearing or feeling super oily.

Good day, We always desire the best possible experience for you. We are truly sorry to hear if you are not happy with your purchase. Rest assured we formulate Mielle without harsh chemicals but with essential oils and beneficial ingredients. We are blown away by how many have enjoyed this product, but we greatly appreciate that not every product will work for everyone or the same when a number of fluctuating factors affect our hair success -- routines/regimes, hydration, nutrition/diet, sensitivities/tolerances, current hair needs/conditions, hormone changes, stress... and more. Even the types of products we need in different seasons can vary. You may know.. Hair shedding is a natural process. According to the American Academy of Dermatology Association, it's normal to lose between 50 to 100 hairs per day. But… Various factors, like hormonal changes, heredity, medications, stress, poor nutrition, and excessive styling, can contribute to increased hair shedding. please Please know… Our products undergo rigorous and frequent internal and 3rd party testing to ensure their safety and efficacy. Mielle Rosemary Mint Oil and Shampoo have been dermatologically tested for skin safety, and no indications of irritation or sensitization were found. Additionally, these products have been tested for eye compatibility in case of accidental exposure, yielding favorable results. None of the negative experiences alleged have been medically confirmed as health issues caused by our products. We always encourage you to seek professional advice from a doctor or board-certified dermatologist for an accurate evaluation and personalized recommendations.
