Bleaching works by mixing Powder Bleach with 20 Volume Developer to activate the lightening process. Most bleach kits need 30 vol developer just to start lifting, which can be harsh. The 2.Oh! Bleach Kit is different — our formula is engineered to lift beautifully even with 20 vol, making it far more gentle on your hair. The science behind it: Bond-Protecting Plex Technology helps protect internal hair bonds while Argan Oil cushions the hair fiber, keeping it soft and flexible. And Comfort Fragrance Tech removes the strong, unpleasant chemical smell other bleaches have.

Apply to dry hair, mid-lengths & ends first, then roots. Keep checking as it lifts but never exceed 45 minutes. When done, shampoo thoroughly with the 2.Oh! Anti Yellow Shampoo. This tones out brass and ensures a cleaner, brighter lift — the perfect base for golden, pastel, or vibrant fashion colors. Finish with the 2.Oh! Reconstruction Mask so your hair feels smooth, strong, and healthy after bleaching. High lift, low damage — that's what makes this system superior.

Always mix in the professional 1:2 ratio — one scoop of Powder Bleach with two parts 20 Volume Developer. This gives the optimal creamy consistency for even application and proper, controlled lightening. Because our bleach is designed to lift effectively with just 20 vol, hair experiences far less chemical stress compared to 30 vol systems.

Bond-Protecting Plex Technology helps protect internal hair bonds while the pigment breaks down, while Argan Oil keeps hair moisturized during processing. That means you get a strong, clean lift without your hair feeling brittle or rough. Once the desired lift is achieved, shampoo thoroughly with 2.Oh! Anti Yellow Shampoo to tone brassiness and keep the lift bright, then follow with the 2.Oh! Reconstruction Mask for nourishment and shine.

We highly recommend using only 20 Volume Developer with the 2.Oh! Bleach System. The formula is designed to deliver powerful lift with lower strength developer, unlike traditional bleach systems that require stronger, more damaging 30–40 vol. Choosing a higher volume developer will not give better results — it will only stress the hair more.

The difference lies in the science: Bond-Protecting Plex Technology keeps inner hair bonds safe, while Argan Oil prevents dryness and roughness during processing. Comfort Fragrance Tech ensures a pleasant bleaching experience too. After processing up to 45 minutes, shampoo with 2.Oh! Anti Yellow Shampoo to neutralize any brass. This paired system offers the safest path to lighter, brighter hair at home.

Stick to the 1:2 ratio — one part Powder Bleach mixed with two parts 20 Volume Developer. This ensures proper activation so the bleach works effectively without drying out or patching. Thanks to the advanced formulation, 20 vol is enough to achieve a visible, high-quality lift, making the process far less damaging than high-strength alternatives.

Our Plex Technology supports internal hair bonds while lifting, and Argan Oil helps maintain softness. When the lift is complete, shampoo thoroughly with 2.Oh! Anti Yellow Shampoo to tone and brighten the hair instantly. Following with the 2.Oh! Reconstruction Mask completes the cycle — healthier-looking blonde that feels as good as it looks.

If you're lightening hair for the first time, the 2.Oh! Bleach Kit makes it safe and easy. Apply on dry, unwashed hair, section neatly, and apply mid-lengths and ends first. Mix using the 1:2 bleach-to-developer ratio, keep checking every few minutes, and never leave bleach on for longer than 45 minutes. Crucial tip: If you want to go lighter, bleach again later — never leave bleach longer. Healthy hair always comes first.

Bond-Protecting Plex Technology keeps the internal hair structure protected while bleaching does its job. Argan Oil helps maintain softness and movement, so your hair doesn't feel stiff afterward. Once processing is complete, shampoo thoroughly with 2.Oh! Anti Yellow Shampoo to tone brass and give a brighter blonde result. Finish with 2.Oh! Reconstruction Mask. With high lift, low damage, this kit is designed for beginners who still want professional-level results.
