Kerastase vs Pureology Shampoo

When you have hair that is begging for some TLC, it’s important that you are addressing it with every step of your hair care routine. You shouldn’t rely on just a single treatment to do all the heavy lifting - your shampoo and conditioner should be pulling their weight, too.

That’s why we love that so many brands—such as Pureology and Kerastase—boast multi-step systems that make it incredibly easy to *fully* address your hair-care concerns. Speaking of which, the first steps of their best-selling hydrating ranges are the Pureology Hydrate Shampoo and the Kerastase Nutritive Bain Satin.

The Kerastase Nutritive Bain Satin is formulated to target dry and damaged hair. It cleans the hair and scalp, whilst injecting moisture back into the hair. The shampoo also works well as a detangler.

The shampoo contains a variety of natural ingredients to deliver results. One key ingredient is Iris rhizome extract, which provides deep moisture. It also contains resin from a Benjoin tree which repairs the hair follicles and restores shine.

To use the shampoo, begin with wet hair and massage a coin-sized amount into your scalp, before rinsing thoroughly.

Users with frizzy hair have noted the shampoo immediately reduced frizz and revealed softer and stronger hair.

The Pureology Hydrate Shampoo is a rich shampoo that hydrates and repairs broken and dry hair. It uses Pureology’s Antifade Complex which protects coloured hair to retain its vibrancy.

The shampoo features natural wonders such as jojoba, green tea, and sage. These ingredients nourish and soften the hair follicles. If you enjoy aromatherapy, this shampoo has a calming blend of lavender, patchouli, and bergamot.

The formula is also 100% vegan and cruelty-free, Finally, it is free from parabens and sulfates, which can dry out your hair.

Pureology recommends that you lather the shampoo into wet hair from scalp to ends, before rinsing away.

Both shampoos are available for more or less the same price per fluid ounce.

In my opinion, the Pureology Hydrate Shampoo is the better choice. Although the Kerastase formula is excellent, the Pureology formula is naturally reparative and smells divine. It contains a better range of hydrating ingredients that are great for your hair. You also get slightly more shampoo than with the Kerastase shampoo.

Kerastase vs Pureology Conditioner

No good hair care system is complete without a conditioner. I'm personally a fan of mixing and matching my shampoos and conditioners to address multiple different needs. For example, when using a clarifying shampoo, you don’t necessarily also need a clarifying conditioner. *But* when it comes to dry/damaged hair, it is definitely wise to complete the full multi-step routine to ensure you get the expected results.

Let’s compare the Pureology Hydrate Conditioner and the Kerastase Nutritive Lait Conditioner.

The Kerastase Nutritive Lait Conditioner is a silky, moisturizing treatment. It works on all hair types but is targeted towards dry, damaged hair because of its reparative technology.

Online reviewers have praised the conditioner for quickly restoring moisture to their hair and making the hair look and feel much healthier.

It features Kerastase’s Iris Royal Complex which contains lipids and proteins, which cleanse, nourish, and protect the hair. It also contains Iris Florentina Root Extract, known to strengthen and soften broken hair.

For best results, thoroughly apply the conditioner to wet hair from the lengths to the ends of your hair. Leave it to work its magic for 2-3 minutes before rinsing away.

The Pureology Hydrate Conditioner is a moisture-rich treatment that smoothes and restores damaged hair. It also uses an Antifade Complex, whilst protecting the color of dyed hair.

It features jojoba which locks in moisture, as well as calming green tea and sage. It also contains mint which is an antioxidant and leaves a fresh smell.

Furthermore, this conditioner acts as a protective barrier against environmental damage. It features a UV filter that protects hair from the sun’s damaging rays.

Vegan customers will be pleased to know that the conditioner is 100% vegan, and contains no animal-derived ingredients or byproducts.

To use this product, simply massage it into wet hair, leaving it in for 1-2 minutes and rinsing thoroughly.

While both conditioners offer powerful hydration, our favorite has to be the Kerastase Nutritive Lait Conditioner. The inclusion of proteins and moisturizing lipids makes for a luxurious formula, and the product is renowned for its softening and reparative effects. While it costs ~$5 more than the Pureology conditioner, it’s a great investment for damaged hair.
