Frequently asked questions

Questions about the Hydrating Mask? Find our most frequently asked questions here. Still need help? Contact us.

How is a hair mask different from a regular conditioner?

A hair mask is more concentrated and meant to be left on longer than a regular conditioner, allowing deeper penetration for more intensive moisture. While conditioner is used with every wash for everyday maintenance, this mask is used less often and is designed to bring dry or sensitive hair back to life.

How often should I use the Hydrating Mask?

Like most hair masks, it's meant to be used periodically rather than daily — typically once a week or every couple of washes — in place of your regular conditioner, since it's a more intensive treatment.

What's the difference between the Hydrating Mask and the Deep Hydrating Mask?

Both masks deliver intense moisture using similar nourishing ingredients. The Deep Hydrating Mask is positioned with extra care for medium-to-thick hair and emphasizes strong, long-lasting moisture and flexibility, while the Hydrating Mask is described as ideal for dry or sensitive hair generally, with a focus on bringing life back to hair that feels dull or fragile. If your hair is thicker or coarser, the Deep Hydrating Mask may be the better fit; for finer or more sensitive hair, the Hydrating Mask may feel gentler.

Will this mask help with dull or dry-looking hair?

Yes — the mask is formulated to restore moisture, smooth hair, and boost flexibility, helping dull, dry hair look and feel softer, shinier, and more manageable.

Can I use this if my hair is color-treated or bleached?

Yes, the Hydrating Mask is safe for color-treated, highlighted, and bleached hair, and is designed to add moisture without stripping color.

This hydrating mask completely revived my blonde hair. It feels incredibly soft, smooth, and deeply nourished without weighing it down.

The Science

A synergistic blend of skincare actives and superfoods

Hyaluronic acid icon describing Blacklight Blonde Science hair products

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 icon describing Blacklight Blonde Science hair products

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 icon describing Blacklight Blonde Science hair products

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 icon describing Blacklight Blonde Science hair products

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.

It is the first mask to actually help my damaged colored curly hair! My stylist wants to cut it out! What!? Not a solution for curly hair. But this mask is the solution!

The Best Hair Mask

Great hair mask. My hair is dry and I find that Blacklight hair care systems help immensely. This mask, to be used after conditioning, then rinse with cool water, softens hair and helps get it back into shape. I love this product!

Quality

Love this product, I ordered it thinking it was something else and tried it. It gave me results right away. I don't use much since I don't have much hair, but it leaves your hair soft and good. Specially since I have blonde and highlights. It usually fades fast, but it keeps the color and doesn't feel like it damages my hair. I am going to buy the leave in spray oil now and see if it leaves it much better.

Can't live without it!

I think its excellent as all the Blacklight line to reduce brassiness. I have fine straight silver hair, and the product line helps maintain the silver color. The mask helps with depositing a little more color and adds softness.

Recommended

I would rate this at 4.5 stars. I am a natural almost black brunette. I went platinum and my hairstylist suggested this. I use it in lieu of normal conditioner.I would honestly say my hair felt like straw, but I assume this was the extreme dye processing’s doing. My hair felt way worse if I used any conditioner or hair mask other than this.I returned to my normal color after a year, with some highlights. I still use this. Not once did my hair turn brassy, which it often did before with highlights.Overall, I think this product saved my hair as much as could be expected. I have thick but fine hair, and it doesn’t weigh it down.

I use for yellowing blonde & hair breakage

I started using this after the bleached areas of my hair started having some breakage,& the front pieces started looking yellow,instead of cool blonde. This product solved both issues! I definitely think purple conditioner works better than purple shampoo,even if I leave the shampoo on for 10min. I use this once/wk,& pile my hair on top of my head and leave it on for usually about an hour. Then,rinse. It makes my slightly yellow highlights cool blonde again,but the biggest problem it’s solved is the hair breakage. It also leaves my hair smelling really good,for days. Highly recommend.

Will this turn my gray hair dark?

Blacklight Blonde Science

Thank you for your question! No - our Hydrating Mask isn't a toner or color depositor, so it won't darken gray hair; it's a moisture treatment for dryness and softness. If you're noticing any tint change, that's more likely coming from a purple/blue toning shampoo elsewhere in your routine, not our Blacklight Blonde Science Hydrating Mask. Have a great day!
