Formulated specifically for fine, thin or fragile hair, including color-treated and straightened hair, where the main concern is a lack of body rather than dryness alone. It's a weekly treatment rather than a daily conditioner, and is less suited to someone with naturally thick, coarse hair looking for maximum richness.

Most deep-conditioning masks are built to add richness, which can flatten fine hair rather than help it. This one is formulated the other way around: silk protein and black caviar extract for strength and body, in a lighter base that's meant to support volume instead of weighing hair down, which is the specific need fine, fragile or thinning hair has that a standard repair mask doesn't address.

• Apply to clean, damp hair, focusing on mid-lengths and ends rather than the roots.
• Leave on for a few minutes to allow the silk protein and caviar extract to absorb.
• Rinse thoroughly with water.
• Use once or twice a week as a treatment.

Pros:

• Lighter formulation than a standard repair mask, aimed at not weighing down fine or fragile hair
• Silk protein and black caviar extract add body and strength without heaviness
• Salt-free, which is gentler on color-treated fine hair

Cons:

• Not formulated as a rich, deep-repair mask, so it's a poor substitute if the main issue is severe dryness or damage rather than lack of volume
• Fine hair can still feel weighed down if overapplied, so a light hand at application matters
