Milbon Smooth Weekly Booster for Coarse Hair — 4 x 0.3 oz vials, intensive smoothing & softness

Milbon Smooth No.4 Weekly Booster is a salon-grade weekly deep-conditioning vial treatment formulated to smooth and soften coarse hair when used with the SMOOTH homecare line.

This four-vial kit contains 4 x 0.3 oz single-use boosters designed as step 4 in Milbon’s professional three-step deep conditioning system. Each vial delivers an intensive weekly boost that targets coarse strands, improving manageability, reducing roughness, and enhancing silkiness for up to five weeks of at-home results when incorporated into your SMOOTH routine. The concentrated formula is intended to be used after the in-salon or at-home preparatory steps to lock in conditioning benefits.

How does this weekly booster fit into my haircare routine?

Use one vial once a week following the recommended three-step Milbon deep conditioning protocol or after using the SMOOTH homecare products. It’s meant as a targeted reinforcement to maintain salon-level smoothness between professional treatments.

• Use one 0.3 oz vial per week for five weeks of treatment.
• Apply after cleansing and the conditioning step for best absorption.
• Works alongside Milbon SMOOTH shampoos and conditioners.
• Designed for single-use to ensure fresh potency each application.

What improvements can I expect for coarse hair?

How do I apply the vial for best results?

• Concentrate on coarse mid-lengths and ends where smoothing is required.
