Kerastase’s Resistance Therapiste Influenster VoxBox

I’m back with my third Influenster VoxBox, this one brings the oh so luxurious Kerastase’s Resistance Therapiste line!


Can you feel the luxury?

I’ve seen the Kerastase line around but never really looked into it or tried it, so when Influenster sent me an email saying I was in their upcoming campaign with them I was pretty intrigued. But what was even more intriguing was the fact that this line operations on reverse washing methodologies.

In case you’ve never heard about reverse washing, the basic idea of this method is to use your conditioner BEFORE you shampoo. The reasoning (that I’ve seen cited the most) is by conditioning first, then washing, you wash off the weight of the conditioner and end up with clean, moisturized, and weightless hair.

The idea of conditioning before shampooing made me uncomfortable. My hair lives off of conditioner, ending on a shampoo note just sounded like a train wreck waiting to happen! But was it?

Kerastase’s Resistance Therapiste:

What it is: A hair care line for over processed and damaged hair

 Soin Premier Therapiste (Conditioner): 

“Reverse Fiber Renewal Care Conditioner created to use before shampoo to protect & repair very damaged, over-processed hair without the weigh-down effect. Acts like a caring gauze to protect the fiber before shampoo and hair is soft, with a lightweight touch”

 –  Kerastase-USA Product page

Bain Therapiste (Shampoo):

Extra Creamy Shampoo Fiber Renewal Care for very damaged, over-processed fine, medium and thick hair.The 1st shampoo with a unique jellified texture that repairs the hair fiber while gently cleansing. Envelops the fiber during cleansing to reduce friction.

The Good:

  • This product smelled pretty divine, my boyfriend complimented me on the scent of my hair after just one wash of this.
  • The ‘Balm” lather of the shampoo was easy to work into hair and felt pretty silky in my hair.
  • Most of my hair felt pretty moisturized after consistent usage.

The Bad:

  • This product stripped my hair color (a purple ombre) out pretty fast…
  • This is actually rather pricey for what it is, in my opinion.
  • Although it helped out my roots and mid shaft, I feel like this was heavy and harsh on my delicate ends.


Final Thoughts:

I found there to be a learning curve (for me) when using this. Normally when I wash my hair I use shampoo only on my  scalp and conditioner only on my mid shaft and ends. I will wash all of my hair with a clarifying shampoo every so often to give it a good clean, but for the most part shampoo isn’t needed on the rest of my hair. So when I tried out this reverse washing method, my hair didn’t feel as nice so I hopped onto the internet to research more about reverse washing and some potential tips. One tip that ended up working for me was to apply generous amounts of conditioner throughout all of my hair and then wash the conditioner out with the shampoo instead of conditioning, rinsing, then shamooing. Not too sure why, but that method resulted in my hair finally reacting to the Kerastase’s hair care line.

My hair has been through a lot of bleaching and a lot of dying. This product helped restore some of my hair’s health, but it didn’t perform like what I would think a $42 conditioner and $42 shampoo would. Also, the fact that it stripped my hair color out super fast is a huge downside for me.

But I think if you have a more permanent color in your hair (think anything but red, purple, blue, green, and so on) then you may not experience the same color stripping I did. And if your ends are not bleached to hell and back, then you may also not find this hair care system too heavy for them.

I would give this hair care system a solid 3.5 out of 5.

It performed pretty well, but I was one tough customer with my hair demands. Frankly, I’m not entirely sure if I will purchase this hair care line for myself in the future. However, I am curious about their hair serum and products from their other lines. I do spot them often at Nordstrom’s Rack and will more than likely end up picking up other products to try from them there.

Have you tried any of Kerastase’s products? How did you feel about them? Let me know!
