The Bigger, Better-Value Size of a Salon Favourite Argan Treatment
milk_shake Argan Deep Treatment in the 500ml size is the smart choice for anyone who has already fallen for the 200ml and wants to make sure they never run out. Packed with organic Argan Oil and wheat proteins, this deeply nourishing mask tackles frizz, dryness and hard-to-manage hair from the very first use — sealing the hair cuticle to lock out frizz and lock in moisture for hair that feels noticeably softer, shinier and more manageable before you have even picked up a brush. The same rich, warm fragrance and the same gorgeous results as the 200ml, in a size that makes more sense for regular use. Find it alongside other hair masks and treatments in our full range.
Organic Argan Oil and Wheat Proteins for Deep Cuticle Sealing
Organic Argan Oil is rich in fatty acids, Vitamin E and antioxidants that penetrate the hair shaft to nourish deeply from within — sealing and smoothing the cuticle for a surface that resists frizz and humidity while locking moisture inside the hair where it belongs. Wheat proteins complement the Argan Oil by strengthening the hair fibre and improving elasticity, making hair more resilient and manageable with every treatment. For thick, wavy or unruly hair that tends to puff up in humidity or feel rough and dry between washes, the cuticle-sealing action of this mask makes a visible and tactile difference that other treatments simply do not match.
Colour Protection and Long-Lasting Vibrancy
The Argan Deep Treatment also helps preserve colour vibrancy between appointments — the sealed cuticle it creates slows the fading caused by washing, heat styling and environmental exposure, keeping colour looking fresher and more vibrant for longer. For colour-treated hair that benefits from both intensive conditioning and reliable colour care, this is a weekly treatment that earns its place in the routine at every level. For the complete milk_shake Argan experience pair with the milk_shake Argan Shampoo and Argan Oil.
How to Use milk_shake Argan Deep Treatment
Apply to clean, towel-dried hair from mid-lengths to ends and leave for a few minutes before rinsing thoroughly. Use once or twice a week as an intensive frizz-fighting and nourishing treatment. For a deeper conditioning result on particularly thick or dry hair, leave on for longer or apply under heat for enhanced penetration. Also available in the 200ml size.
