مصل جل لفروة الرأس Kerastase Specifique Hair Serum

The serum is great, but the scent is very strong and sharp, making it difficult to get used to. It's not advisable to use perfume with it, as it would create an even stronger and mixed odor.

I received a 30ml sample of this serum for testing. The scent is absolutely amazing, just like the entire Specifique line, and I really love it. It lasts on the hair until the next wash. The bottle is made of glass. The serum absorbs quickly and doesn't make the hair greasy. It slightly prolongs the freshness of the hair and does give a little bit of volume. One major downside is that denatured alcohol is listed as the second ingredient. I highly doubt that people with problematic scalp skin will appreciate this. Also, personally, I find it inconvenient to use the dropper. It's difficult to draw the necessary amount up to the mark (either too much or too little is drawn). Additionally, hair falls out while massaging it into the scalp. And you also need to get into the habit of applying it every day. I deducted stars for the alcohol being the second ingredient and the inconvenience of use, personally for me.

The smell is excellent! I really like it!
I started using it not long ago, so it's too early to talk about hair growth enhancement.
But one thing I have definitely noticed is the absence of dandruff this winter. And, by the way, my hair gets less static.

I was not expecting to like this serum so much. For my dry and sensitive scalp, it gives the same effect as a very good moisturizing face mask. It provides a fresh feeling all day long. It eliminates tightness and dryness. Upon application, there is a slight cooling sensation, so it will be especially pleasant to use in the summer. Hair looks more alive. More shine and volume. The serum is thick and gel-like, but not sticky or greasy. It absorbs well and has an unusually pleasant aroma. The only thing is that I needed 3 pipettes for my entire head. I had to apply more.

After giving birth, the skin on my face and head became very dry. Plus, I recently had COVID. What a combo. Even my forehead, which was extremely dry and causing discomfort, was improved by this serum. It reduced dryness and itchiness.

Applying it is very easy and convenient. The design is fantastic.

It doesn't leave hair greasy, which is important.

I must mention the scent separately - it smells incredible. This is a huge plus for a mom on maternity leave.

I have been testing the POTENTIALISTE serum for almost 3 weeks now, using it daily. The effect was noticeable from the first days. After wearing a hat, my scalp was not in the best condition, but after using the serum, the itching subsided, and my skin felt moisturized and more comfortable. It is easy to apply and convenient to use thanks to the pipette, and I only need 2-3 drops for my scalp, so it is economical. The gel-like texture is pleasant. I must mention the amazing scent of the serum, which lingers on the hair for a long time. I definitely recommend this gel serum.

Magic for sensitive scalp. I use Dermocalm shampoo and Blonde Absolute mask/conditioner for blondes in my skincare routine. But this serum works wonders on the skin. It especially saved me after coloring my hair, when my scalp was irritated and itchy for a week. And the most important thing is that it doesn't weigh down the roots. I highly recommend it for those who are concerned about their scalp.

Three weeks ago, I was experiencing dryness, tightness, itching, and dandruff, so this product came just in time. After using the serum for a week, my hair miraculously started to fall out less, became thicker, and more manageable. Volume appeared. The scalp became moisturized and nourished, and dandruff disappeared. I am thrilled.

I want to share my impressions after using it for three weeks.

Suitable for dry scalp, it immediately provides a softening effect upon application. The scent is amazingly beautiful, and it has a light, gel-like texture.

I received this serum for testing and I was amazed. I will definitely purchase this product again. It is very convenient to use thanks to the dropper. I noticed the effect after a week of use - my hair does not get greasy, my scalp is hydrated, and the scent is amazing. If there was a perfume with the same scent, I would buy it too. Thank you Kerastase for this fantastic product!

Kerastase never ceases to amaze! I received this serum for testing and I am very satisfied! Firstly, the packaging is convenient - the product is applied directly to the scalp using a pipette (no need for a sponge or to mess up your hands, which reduces unnecessary waste). Secondly, the serum does not affect the frequency of hair washing (I thought I would have to wash it every day) and does not cause dandruff. Thirdly, the result is no more scalp itching (which I had before from the shampoo), the hair has become obedient and "alive", and as an additional bonus - the scent! I am very pleased with this serum!

I have been using this serum for 1.5 weeks. It doesn't make my hair greasy at all (which was my main concern), and I feel less dryness on my scalp after washing with this serum. It's very convenient to apply the serum with the applicator. The scent is amazing, I love it! My friends even ask me what perfume I'm wearing. My hair reaches below my shoulder blades, it's not dyed, and tends to get oily. I am satisfied with this serum!

This product provides excellent moisturization and soothes the scalp without causing dandruff. It effectively eliminates any feelings of tightness on the scalp and is easy to apply. As a bonus, it has a pleasant scent.

Interesting and new product from Kerastase. Provides noticeable comfort and hydration to the scalp. Hair stays fresh for longer and, as a bonus, the serum adds root volume to the hair. I recommend it as an additional care product.

I am using an interesting new product for scalp care called Potentialiste. The serum is applied with a convenient applicator. Since I have thick hair, three pipette applications are enough for adequate distribution on the scalp. The product has a pleasant scent that reminds me of natural healing, which I really like. The sensation of the serum when applied is neutral. It has a consistency similar to a medium-thick gel, not too dense or too runny, and it applies optimally. After applying, I gently massage it into the scalp with my fingers. It does not make my hair greasy and provides a comfortable feeling for the scalp without causing dryness. I highly recommend trying this additional scalp care product.

I have an oily scalp. I was afraid that using this product would make my hair worse and make it look dirty. BUT! My hair stays fresh even longer after using it!

The serum itself is quite thick, I apply it after blow-drying my hair and massage my scalp a little.

But the special pleasure comes from the scent, it's just love))

I received this serum in a 30 ml format. This size is enough for a week-long course. The serum has a pleasant perfumed scent. I used it according to the instructions: applied it daily to dry scalp, making small parts. After a week of use, I noticed that my scalp started getting less dirty, and the itching and irritation disappeared. I recommend this product if you have issues with itching, dandruff, or if you simply want to improve the condition of your scalp.

I really like products from the Kerastase brand. Thank you for giving me the opportunity to test the serum. It is amazing, from the packaging to the scent!

I have dry hair and a dry scalp. I wash them every 5-7 days. And often after washing, I feel tightness and even itching. It's been a week since I started using this serum and I can't be happier. I think I found my solution! My skin feels like it can finally breathe, and my hair at the roots has come alive, becoming more nourished, denser, and more elastic. Volume and shine have appeared as well. The sensations are very pleasant, with a refreshing feeling and no itching. I didn't even expect this serum to solve my problem and eliminate the constant discomfort so quickly. The fragrance is especially amazing - it's divine, reminiscent of the scent of expensive perfume, and it's long-lasting (I can still smell it at the end of the day).

Good day!
The Kérastase Universal Scalp Serum worked perfectly for me. I have been dyeing my hair for a long time, and I always lacked moisture, and dryness bothered me. This product solved these problems. It provides moisture, eliminates dryness, and reduces hair frizz. I can't even imagine how I lived without this serum before. I definitely recommend it! Kérastase, you are the best!

The glass packaging is beautiful and the dispenser is of high quality, making it very convenient to use. I have a tendency towards seborrhea and dandruff on my scalp, so I applied it to my hair when it was as clean as possible, and it left a pleasant moisturizing feeling. The texture is not oily and it is easy to apply. It is nice to pamper oneself with such a product, the scent is bright and fresh.

The serum is simply amazing, the scent is unreal and I really liked it.

The serum is absolutely amazing, the scent is unreal and stays with you. I really liked it.

This serum works wonders for the scalp. Previously, I had to wash my hair every other day, but with this product, I can easily go three days without washing and my scalp feels amazing. And if you also use the shampoo from this line and the brush for foaming the shampoo, your morning hair care routine will turn into a spa procedure, as the huge advantage of the Specifique line products is the scent - fresh and invigorating, long-lasting but not overpowering.

I received a sample of the product for testing, and the fragrance is unparalleled. The initial impressions are superb, and I will eagerly await the results and other new releases from my favorite brand, which I have been loyal to for 6 years and counting!

This is simply amazing! Starting from the application ritual, the pleasure from the texture and aroma... and I must also mention that my skin has become more vibrant, the feeling of tightness has disappeared - after all, it's winter, paint, dry air in the rooms. I am very satisfied!

Thank you, Kerastase, for the gift and the wonderful opportunity to try out this new product! I have a sensitive scalp, so this is exactly what I needed. I will continue using it and will share my impressions after the course.

From what I can mention now, the packaging is beautiful, with a bottle and pipette made of glass - impressive! And the fresh floral scent is so delightful that I no longer need perfume with this serum.

This is an excellent product. It calms the skin completely, and the scent of the Kerastase brand in all their products is very rich. It lingers on the hair until the next wash, which is super cool.

I received this product to try out, and I am very satisfied. The scent is very pleasant, with a herbal note. There is no stickiness after application, and it leaves my hair feeling clean and pleasant.

I received my new product today and I am absolutely thrilled ❤️ It has a convenient dispenser, a good composition, and an incredible scent! It feels pleasant to the touch, absorbs quickly, and doesn't leave a sticky residue. I will write about the results after three weeks.

I received a miniature version of the product today for testing, thank you very much. The volume of 30ml is sufficient to feel the effect, so I will test it out. I will write about the results in a week, but I am already confident that I will like it. After trying out other testers, I chose and purchased full-sized products for myself - a shampoo for weakened hair, a shampoo for blondes for my mom, and a heat protectant for my daughter. Thank you for giving us the opportunity to test your product.

I really liked this new product! It is very easy to apply, and my scalp feels noticeably fresher and calmer! It doesn't weigh down my hair at the roots. As always, this brand's products are top-notch. I highly recommend it!

Ladies, I highly recommend it! My hair looks fresher and healthier. I use it every day. The texture is light, and you only need to apply 2-3 drops and massage it into the scalp. I am satisfied!

This serum has a luxurious and delightful scent. The applicator for applying it to the scalp is convenient. The skin becomes moisturized, eliminating any tightness or discomfort. It soothes and has an antioxidant effect. I was extremely satisfied after using it. I wholeheartedly recommend it!

A good serum with a convenient dispenser. The scent is luxurious, simply incredible. The scalp feels soothed, and the tightness after hair drying is gone. The consistency is not sticky and moisturizes the hair at the roots. It feels like a spa treatment until the next wash. And a great bonus is using it as a brow care product. :)
