A few months ago I placed an order from for some Kristin Ess hair care products including The One Purple Shampoo, as well as The One Signature Shampoo and Conditioner. Today I’m sharing my review and experience with the latter.


Kristin Ess is a celebrity hair stylist who started her own line of affordable hair care products and tools in 2017.  Her line includes everything from shampoo and conditioners, styling products, hot tools and hair glosses.  You can find her products on her website, at in Canada, and at Target in the US.


The One Signature Shampoo + Conditioner retail for $12.99 each and contain 10 fl oz / 296 ML of product.


The One Signature Shampoo:

From the website:

“The shampoo for pretty much anyone. The best thing about this formula is it gets your hair super clean but also leaves it feeling moisturized and looking shiny. It’s hard to find a shampoo, particularly a sulfate-free shampoo, that can do both so well.


  • For all hair types
  • Lightly clarifying
  • High lathering
  • Safe for daily use
  • Sulfate-free
  • Cruelty-Free

The One Signature Conditioner

From the website:

The conditioner for pretty much anyone. This formula leaves the hair super shiny and smooth. It’s weightless, softening and it rinses clean. This can be used daily and will not cause build up.


  • For all hair types
  • Weightlessly moisturizing
  • Smoothing + softening
  • Shine renewing
  • Sulfate-free
  • Cruelty-Free

Both products contain Zip-Up Technology: Kristin Ess’ proprietary strengthening complex designed to “zip-up” split ends while targeting weak areas of the hair, smoothing the appearance of damaged cuticles and helping to protect hair from environmental stressors and color fade.”

I’ll preface my review by sharing my hair type: it’s fine but I have a decent amount of it, colour treated (blonde highlights) and I heat style several times a week. Overall I’d say it’s generally in good health but it can damage and dry out easily.

When I purchased these, I was just looking for a good, basic everyday shampoo and conditioner; it sounds like a simple request but honestly, I’ve found this can be really hard to find.  Most products are trying to fix something with your hair – add volume, colour-protect, repair damage, etc.  I have enough of those and just wanted something really simple.  I

I’m happy to say that this has delivered; I use them together, on average, about once a week and I’m always impressed with the condition of my hair afterwards.  It just feels clean and also healthy – there’s definitely some added shine and softness.  I find the shampoo gentle but entirely capable of cleansing my scalp of 2 days of dry shampoo residue, while the conditioner is lightly moisturizing without weighing my hair down.

I’m also a fan of the packaging – the blush pink looks so pretty in my shower and the bottles have that soft-touch rubberized feeling to them.  The packaging definitely has that higher-end feel to it so I think she nailed it there.

The one and only complaint I have – the scent.  This is one of the strongest scented shampoos/conditioners I’ve ever used and it’s not a scent that I find appealing. The best way I could describe it is like a sickeningly sweet cucumber melon candle from Bath & Body Works. On the bright side, I don’t find the scent lingers in my hair.  My hair definitely has a bit of a fragrance after but only if I hold my hair right up to my nose and even then, it just smells slightly perfumey and refresh (thank Dog!).  That said, if you are sensitive to fragrance, I think I’d stay clear of this.


I will definitely be repurchasing both of these once I’ve finished with them and I’d recommend them for you, if, like me, you’re looking for a good basic shampoo and conditioner and are not sensitive to fragrances (this is important!).  I’m looking forward to trying some of the other products in her line, including her Texture Spray and Detoxifying Bubble Hair Mask!

Have you tried anything from the Kristin Ess line?  Let me know below!

    Thanks for the review! I keep eyeing the Kristin Ess line on ever since I found out from you that they stock the brand, but right now I have too many hair products open to justify buying more. Great to know that this is a basic shampoo/conditioner duo. I’m interested in the texture spray as well!
