Today I am sharing my Nécessaire scalp serum review.
I am so excited about this post because this scalp serum has worked SO well for me.
Last winter, I had noticed that my hair was looking kind of thin around my hairline and part. I conducted a casual round of research (as one does) and learned that scalp serums can help strengthen hair and encourage growth. I had never used a scalp serum before and felt *instant* FOMO.
In my research, I saw a few different sites mention Nécessaire’s scalp serum. Then once I read through the reviews on Sephora’s website, I decided to give it a go.
Nécessaire Scalp Serum Review
Given this was my first time trying both a scalp serum and anything from Nécessaire’s line (although it seems like I can’t go on Instagram without seeing someone post about the Nécessaire body wash!), I didn’t go in with a ton of expectations.
But after about 3 weeks of daily use, I started to notice that my hair was growing like crazy. And my husband–who has never, not once, noticed my hair–randomly commented on how long my hair was getting.
Then, 3 weeks after that, he mentioned it AGAIN, specifically using the words “long” and “healthy.” I was shocked and immediately walked to the bathroom to take a few selfies so I could compare.
Sure enough, it looks like my hair has grown nearly two inches (!) since I started using the serum at the end of December. And my hair is SO much healthier. I’ve also noticed quite a bit of new growth along my part and hairline.
I didn’t do a great job of getting “before” pictures because I wasn’t expecting the results to be so extreme, but you can definitely tell a major difference in the photos I’ve included in this post.
In today’s review, I’m sharing some information about the product and how I’ve used it these last six weeks.
Packaging
This serum comes in a glass bottle (I love this obviously) and includes a dropper for easy application.
Consistency
The consistency of this serum is super thin–almost like water! The formula is oil free, and the product absorbs quickly which is nice.
I had a bunch of people ask me about this on Instagram, but keep in mind that I have a very high tolerance for greasy hair and usually only wash it once or twice a week. I have, however, noticed that the product absorbs really well on the first couple of nights after a hair wash–it looks like my hair is wet getting into bed but it’s dry by morning. By day three or four, though, my hair does seem to feel a bit greasier than it normally would. Also, it’s worth noting that I use a lot of product at once, and if I had been more conservative in my application then my hair would have lasted longer before getting greasy.
Scent
This product has no scent whatsoever and is completely fragrance-free.
Ingredients
This scalp serum is made with a clinically proven 5% biomimetic peptide (acetyl tetrapeptide-3) that supports hair growth. I learned that this is a “signal peptide” that triggers our skin’s own collagen production and promotes follicle health. Cool, right?
This light serum is infused with 1% hyaluronic acid (7 molecular weights) for a boost of hydration and green tea and celery seed extract which help soothe itchy, flaky, and dry skin.
I read on Necessaire’s website that they run a tight ship when it comes to ingredients. Everything is formulated to the EU’s beauty standards which tend to be much more stringent than ours here in the US.
Price
Nécessaire’s scalp serum costs $45 per 1 oz bottle. I have applied this serum generously each night for the last six weeks and am just now nearing the end of the bottle.
A quick price comparison of a few of the other big players in the scalp serum space: Vegamour retails for $64 for a 1 oz bottle, and Divi costs $48 for a 1 oz bottle.
Given the amount of product I got with Necessaire’s bottle combined with the results I experienced from just that one bottle, I’d say this scalp serum is pretty well-priced.
Effectiveness
I have been so impressed with this scalp serum. My hair is healthier than ever and has grown so much.
Of course, it’s always good to keep in mind that a lot of factors go into a healthy head of hair and I’d be remiss not to mention this. I don’t think anything is going to be a quick fix, but this serum, combined with lots of clean protein, sufficient hydration, and a consistent sleep schedule, has definitely been very effective for me.
I wish I had known about this scalp serum in the height of my postpartum hair loss–I definitely feel like this product would have helped speed things along.
How To Use Nécessaire Scalp Serum
Use before bed
I apply this serum every night before bed. The serum does make my hair look really wet at first, so I like to let it absorb overnight.
I try to do this at the same time I do my nighttime skincare routine so it doesn’t feel like a huge extra step before bed.
How to apply the serum
The serum is really easy to apply to either damp or dry hair.
I run the dropper through my scalp, squeezing the product as I go. I usually run it from front to back in a few different sections, focusing on my part and hairline. Then, I massage it gently with my fingers before I use a brush to comb everything through.
If you’re extra like me, pair it with a hair oil
I also apply a hair oil each night–I LOVE this one from Kérastase. After I apply the scalp serum to my roots, I use 1-2 pumps of this oil and work it through the bottom 2/3 of my hair.
Then, I braid my hair and secure it with a silk hair tie. Do I look like a founding father heading into bed each night? Yes, but if Tyler was going to bail on account of my beauty antics he surely would have by now.
Is Nécessaire Worth It?
This product has been such a pleasant surprise for me. I definitely think it was worth the price for the results I got from just one bottle. My hair feels the healthiest and thickest it’s been since I started having kids.
Where To Buy Nécessaire Products
This scalp serum is available at Sephora and Amazon. You can also purchase the product on Nécessaire’s website (the website is the only place I’ve found a 2 oz bottle available right now which costs $65).
I have heard such great things about Necessaire’s body care products and am dying to try the body serum, body oil, and body lotion next. I’m a sucker for anything with a eucalyptus scent, so it seems to be a match made in heaven.
I hope this review was helpful! Please, please let me know if you try this serum and if it works for you!
