Olaplex Moisture Mask 4 In 1

Bond-Building Deep Conditioning Mask with Ceramides and 11 Amino Acids

Olaplex 4-in-1 Moisture Mask is a deep conditioning treatment that combines OLAPLEX bond-building chemistry with a high-load moisture system. It pairs Bis-Aminopropyl Diglycol Dimaleate with Ceramide AP, Ceramide NP, Panthenol, Squalane and 11 amino acids to rehydrate the cortex, smooth the cuticle and reinforce the strands left fragile by colour, lightening and heat styling. The 370 ml pro-size pump is built for weekly use on mid-lengths and ends.

Why Choose It?

• OLAPLEX bond-building active (Bis-Aminopropyl Diglycol Dimaleate) reinforces hair weakened by colour, bleach and heat
• Ceramide AP and Ceramide NP support the cuticle barrier to help hair hold moisture
• Glycerin, Sodium Hyaluronate, Sodium PCA and Panthenol deliver water-based deep hydration
• Blend of 11 amino acids — including Arginine, Proline and Serine — supports the keratin protein matrix
• Meadowfoam, rose hip, hemp seed and avocado oils add smoothness and slip without a heavy finish

Best For

Damaged, bleached, colour-treated and heat-styled hair that needs a deep hydration plus bond-reinforcement step. Suitable for weekly use on dry, brittle or porous lengths and ends. Works as the mask layer in the OLAPLEX bond routine.

Apply weekly to freshly washed, towel-dried hair as the mask step of the routine. For deeper bond support, pair with Olaplex Nr.3 Hair Perfector pre-shampoo treatment before washing, then follow with Olaplex Nr.4 Bond Maintenance Shampoo and Olaplex Nr.5 Bond Maintenance Conditioner.

• Shampoo as usual and gently towel-dry hair so it is damp, not dripping.
• Dispense 1–3 pumps depending on hair length and density.
• Work the mask through the lengths and ends, detangling fragile areas with the fingers.
• Comb through with a wide-tooth comb so the product is evenly distributed.
• Leave on for 10 minutes, then rinse thoroughly and style as desired.

Tips

• Concentrate the product on mid-lengths and ends; keep it off the scalp if you are prone to flat or oily roots.
• For very dry, bleached or porous hair, you can extend the processing time beyond 10 minutes.
• Use weekly as the deep conditioning step — alternate with a lighter rinse-out conditioner on other wash days.
