L’Oreal moisturizes, softens, and nourishes the hair. Kerastase, on the other hand, will help repair damaged hair as well as add density to hair.

Kerastase is also great for use as a leave-in treatment for colored hair. Whereas, L’Oreal’s hair color is versatile and easy to use.

Kerastase vs L’Oreal: Which is Better?


This is a French brand that’s as old as L’Oreal. Most of the brand’s products center around the treatment of thinning hair. But there are also a lot of them that are formulated for other benefits such as styling hair and keeping it in tiptop condition.

Here are some of the most popular, best-selling shampoos from this French brand:

Kérastase Resistance Serum Therapiste


For treating harmed hair, Kerastase Resistance Therapist is a genuine distinct advantage. This treatment is energetically prescribed for individuals with exceptional hair harm.

The treatment framework consists of a conditioner and a cleanser. The conditioner is intended to be utilized before shampooing with the goal that it can start to mend the hair and ensure the hair before the purifying procedure.

Kerastase Resistance Therapist is intended to restore Keratin Associated Proteins (KAPs). These proteins normally encompass the hair fiber to keep the keratin building squares flawless.

Verdict on the Shampoo

I have thin, fine hair and have been using Kerastase Densifique Bain Densite for about a month now. I noticed a difference in the appearance of my hair after using this shampoo. My hair looked noticeably fuller and less limp.

I also found that my hair was less easy to tangle and was less likely to fall out in the shower. Overall, I am thrilled with this product and recommend it to anyone with thinning hair.

Kerastase Densifique Bain Densite


Kerastase Densifique Bain Densite is a shampoo that promises to add density and volume to fine hair.

According to the Kerastase website, this product contains an exclusive combination of ingredients that helps to strengthen the hair shaft and improve the appearance of thinning hair.

Kerastase Densifique Bain Densite leaves hair looking thicker, fuller, and more voluminous.

Keratin plays an essential role in helping people achieve healthier-looking locks with fewer split ends while simultaneously boosting volume at the roots.

Keratins are also essential when it comes to maintaining the integrity of your cuticles because they work as natural protectors from environmental damage such as pollution or UV rays from sunlight.

This shampoo promises you will get more body, bounce, and shine after just one wash! It’s responsible for ensuring hair remains strong and healthy by adding strength to each strand of hair.


If you are looking for a shampoo that can help to improve the appearance of thinning hair, Kerastase Densifique Bain Densite is an excellent option.

It is packed with essential nutrients that help to nourish the scalp and promote healthy hair growth.

The shampoo also helps protect the scalp against daily aggressors, which can benefit those who live in polluted or sunny environments.

Kerastase Densifique Bain Densite leaves the hair feeling soft, shiny, and healthy, making it an excellent option for anyone looking for volumized and healthy hair.

Effectiveness of L’Oreal Products

Many women have praised the efficacy of L’Oreal products, claiming it offers them luxury at affordable prices.

The L’Oreal true match Lumi lotion has had women feeling radiant in their skin, while the age-perfect color care has made women maintain colored hair without damage.

Other users also can’t get enough of the L’Oréal liquid and powder foundations. The foundations do not cake, crack, or dry out the skin.

Possible Side Effects of L’Oreal Products

Some customers have reported getting an orange tint after using L’Oréal’s magic skin beautifier.

Others have expressed disappointment over the use of hair products called the Total Repair 5, which has given women acne and bumps on their backs.

The Revitalift eye cream has caused consumers to have redness and a burning sensation around the eyes. The volumizing mascara has been reported to give women severe eye infections.

Men have also complained of breakouts when they use the Men Expert Face Cream. Children using the L’Oreal kids 2 in 1 shampoo claim it burns their eyes, and not only that, but it also makes the hair frizzy.

This is a conditioner and comes in two sizes, 20 and 28Fl Oz for damaged hair. If you’re looking to renew your hair so it becomes shiny, silky and strong, you may want to look into this one.

It’s very affordable and many users compare it to very expensive products that promise the same thing.

Another thing is that many praise it for making being an authentic conditioner that helped their hair feel stronger, softer, and better than before.

You should also be aware that it’s suitable for colored hair and the shampoo is also available at roughly the same price.

L’Oréal Paris EverPure Blonde Sulfate-Free Shampoo

Loreal also has another shampoo called L’Oréal Paris EverPure Blonde Sulfate-Free Shampoo which is specifically designed for blonde hair.

One thing I like about products like this is that they’re specifically designed for certain hair colors and are likely to be more effective than other shampoos that are just safe for use with treated hair.

Again, this shampoo is sulfate-free, so if you want a non-chemical shampoo, this is a good option for you. The formula also includes a conditioner and Loreal recommends using both for best results.

L’Oréal Paris EverPure Sulfate-Free Volume Shampoo

L’Oréal Paris EverPure Sulfate-Free Volume Shampoo

This one is a volume shampoo for those experiencing hair loss or frizz. It’s available in 4 packages with some being a combo of shampoo and conditioner.

Like the Blonde Shampoo above, it’s free from sulfate and goes for an even cheaper price.

Fortunately, it’s also suitable for colored hair, even though it may not be as effective as the one above, especially if you have blonde hair. It’s soft and can help you control hair volume. Try it.

Final Thoughts on Kerastase or L’Oreal

Now that you have a comprehensive comparison of both brands, the next thing is to choose whichever suits your preferences the most. Just ensure you choose something that’s compatible with your skin type and isn’t too expensive for you.

    1. Yeah, Kerastase is a high end line of L’Oreal, as opposed to the professional line that include Matrix, Redken, Pureology. That doesn’t mean they can’t be compared though. For example, Redken and Pureology and Kerastase all have shampoo and conditioner lines that can be compared.

  1. I am a hairstylist trying to find a “L’Oréal” substitute for the Kerastase line “discipline”
    . I can buy wholesale and they have many choices of L’Oréal but not Kerastase
    Specifically . I have a client that used it and wants me to find a substitute .

    1. SalonCentric has a line that is almost the same, L’Oreal Serie Expert line… The hair rep that works there told me they’re almost the same but a less expensive version.. check it out
