Blonde Hair Questions, Answered

Everything you need to know about the The Mask Sale - 20% Off collection before you shop.

How often should I use the Deep Hydrating Mask?

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

How often should you use a repair treatment on damaged hair?

Most repair shampoos and conditioners can be used every wash, while more intensive repair treatments or masks are best used 1 to 2 times per week. Overdoing intensive treatments beyond that can occasionally leave protein buildup, so balancing repair with hydration is key.

How do you know if your hair needs a repair treatment versus a hydrating one?

If your hair feels brittle, snaps easily, or has visible split ends, it likely needs a repair treatment focused on rebuilding strength. If it feels rough or dry but isn't breaking, a hydrating formula may be enough — many people with heavily processed hair benefit from using both together.

Can I use Hydrating Mask 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.

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.

Hair Masks Collection: Repair, Hydrate & Deep Hydrate — 20% Off

Blacklight Blonde Science's hair mask collection is formulated to target the three most common hair concerns: damage, dehydration, and deep moisture loss. Each mask combines hyaluronic acid, ceramides, and superfoods to restore strength, shine, and softness — without weighing hair down or disrupting color-treated blonde tones.

For damaged, brittle, or over-processed hair, the Repair Mask rebuilds strength with ceramide NG for lasting results. For dry, dull hair in need of a lightweight moisture boost, the Hydrating Mask replenishes softness with hyaluronic acid. And for severely dry or chemically treated hair that needs more intensive care, the Deep Hydrating Mask delivers deeper, longer-lasting moisture restoration.

Unlike generic conditioning treatments, Blacklight masks are science-led formulas designed specifically for blonde and color-treated hair, addressing damage and dehydration at the fiber level rather than coating the surface. For a limited time, all masks in this collection are 20% off — no code required.
