FAQs

Hydrating Shampoo

Can I use the Hydrating Shampoo every day?
Yes. The Blacklight Blonde Science Hydrating Shampoo is gentle enough for every wash. For dry hair, 2–3 washes a week is usually best, since washing less often helps your lengths keep their natural oils.

Is the Hydrating Shampoo good for dry blonde hair?
Yes. The Blacklight Blonde Science Hydrating Shampoo is made for dry, dull or frizzy hair, including bleached and highlighted blonde. It cleanses without stripping moisture, and most people feel softer, easier-to-detangle hair from the first wash. Follow with the Hydrating Conditioner for best results.

Can I use the Hydrating Shampoo with a purple or blue shampoo?
Yes, and it’s the ideal pairing. Use the Violet or Blue Shampoo 1–2 times a week to tone, and the Blacklight Blonde Science Hydrating Shampoo on your other wash days. It keeps lightened hair hydrated between toning sessions without over-depositing pigment.

Will the Hydrating Shampoo weigh down fine hair?
No. The Blacklight Blonde Science Hydrating Shampoo has a lightweight formula that hydrates without leaving residue, so fine and thin blonde hair keeps its volume. If your hair is very fine, focus the conditioner on mid-lengths and ends only.

What makes this Hydrating Shampoo different?
It hydrates without heaviness. The Blacklight Blonde Science Hydrating Shampoo combines hyaluronic acid with avocado, rice bran and hemp seed oils to attract and hold moisture in the hair. It’s sulfate-free and colour-safe, developed in our Montréal lab by the team behind Oligo Professionnel since 1986.

The Science

A synergistic blend of skincare actives and superfoods

Hyaluronic Acid

The gold standard in skincare, hyaluronic acids act synergistically on the hair: Water-soluble hyaluronic acid hydrates the surface, while oil-soluble hyaluronic acid hydrates from within.

Avocado Oil

Rich in oleic acid—one of the only fatty acids small enough to permeate the hair shaft—avocado oil conditions from within, minimizing water loss and frizz and maximizing hydration and shine.

Hemp Seed Oil

Rich in fatty acids and proteins, hemp seed oil seals the cuticle and strengthens its structural integrity, restoring hydration and elasticity. Because your blonde should bend, not break.

Rice Bran Oil

Vitamin-rich and lightweight, rice bran oil coats the hair and seals the cuticle. Less frizz and static, no greasy residue—just silkier, shinier hair. It’s hydration without the heaviness.

Great product. My hair wasn’t as dry after styling

Thank you for your wonderful review! We're so glad our Hydrating Shampoo helped improve your hair after styling. We appreciate your support!

I’m really enjoying this shampoo! It has the same lovely, subtle scent as the hair mask, which makes using the two together feel like a little self-care ritual. It leaves my hair feeling clean without feeling stripped or dried out. Paired with the hydrating mask, my hair is finally getting the moisture it’s been craving. So far, I’m impressed with this line!

This is exactly what we hoped people would feel using them together! Clean but not stripped is the whole goal, so hearing that means a lot. Thanks for taking the time to write this 💛

Really like this shampoo

My hair is pretty dry from highlighting it and this shampoo leaves it feeling soft. Doesn't feel stripped after washing.

Would recommend

Smells really nice and doesn't make my scalp feel dry. I do still need a good conditioner but I'm happy with it.

Works great with tape wefts and makes hair so soft

Nice shampoo

I like it overall and my hair feels hydrated. Just wish it lathered a little more but I'd still buy it again.

Good for my blonde hair

Been using this for a few weeks now and so far so good. My hair feels cleaner without getting all tangled up.

I like the shampoo i have colored highlights in my hair . Keepers the color longer with the shampoo and the conditioner for hydrating love it

We're happy to you love our Hydrating Shampoo & Conditioner!

Finally found one I like

I've tried so many shampoos for my dry hair and this one has been great. Even my ends feel less rough than before.

Love this shampoo, my hair feels so much nicer now.

Excellent! Buy it!

Good but took some time

At first I wasn't sure it was doing much but after using it for about 2 weeks my hair definitely feels softer and smoother.

Finally found one

I've gone through so many hydrating shampoos that either made my hair greasy or didn't hydrate enough. This one is a really good balance for me.

Pretty happy with it

I like it! My hair feels softer and doesn't get as tangled after washing. I do still need a mask on my really dry ends.

Good for my blonde hair

I wash my hair 2-3 times a week and have been using this for a few weeks. My blonde feels healthier and not nearly as dry anymore.

Simple but really good

Nothing complicated, it just leaves my hair clean, soft and hydrated. Exactly what I wanted.

My ends feel way better

My ends usually feel pretty rough after shampooing but not with this. Hair feels soft even before I put conditioner in.

Nice shampoo

Definitely more hydrating than what I was using before. Took a few washes before I really noticed a difference though.

Great everyday shampoo

I've been using this every wash for about a month now. Cleans really well but doesn't leave my hair with that stripped feeling.

So far so good

Only used it twice but my hair already feels less dry. Really liking it so far!

Didn't expect to love it this much

My hair has been super dry from highlights and honestly I wasn't expecting a shampoo to make much of a difference. After a few washes it feels noticeably softer.

Shampoo that hydrates well

It does what it says simple

Recommendation from my hairdresser

Everything about this shampoo feels premium

Highly recommend

It really helps with dryness and keeps my hair feeling silky

Soft Hair

I have fine blonde hair and most hydrating shampoos make it flat, but this one doesn�t at all.

Finally Hydrated Again

My hair feels softer, smoother, and way more hydrated without feeling heavy

Best Shampoo

This is the third time I buy this shampoo. It smells great and it lasts a long time for me. I have curly and blonde hair and it was recomended from my stylist.

Can't thank you enough

This saved my dry hair

The same as what I get from the salon

Great
