People with fine, limp, or thin hair who want volume and body without a conditioner that weighs hair down. It's a consumer retail product for daily or regular at-home use, not a professional-only treatment, and works best as part of the full High Amplify shampoo-conditioner-styler routine rather than as a standalone deep conditioner for very dry or coarse hair.

The core trade-off this conditioner solves is that most conditioners add softness at the cost of volume, since heavier conditioning agents — and especially silicones — tend to flatten fine hair. This one leans on wheat protein and a starch-based film former instead of silicone to add structure and lift while still detangling, which is why it's positioned specifically for fine or limp hair rather than as a general-purpose conditioner.

• Apply after shampooing to wet hair, massage through, and rinse
• For the full volumizing effect, follow High Amplify Shampoo with this conditioner and finish with a High Amplify styling product
• Avoid contact with eyes; rinse immediately if it occurs

Pros:

• Genuinely silicone-free, confirmed by both Matrix's own marketing and the ingredient list, so it won't cause the silicone buildup that can flatten fine hair over time
• Hydrolyzed wheat protein helps temporarily fortify and thicken the hair shaft for more body
• Lightweight enough not to weigh down fine or limp hair the way a rich, heavy conditioner would

Cons:

• Contains two purely cosmetic synthetic dyes (Green 3 and Yellow 10) that serve no functional purpose
• Has a notably long list of individual fragrance-allergen components, worth checking for anyone with fragrance sensitivities
• Contains hydrolyzed wheat protein, so it's not a fit for anyone avoiding wheat-derived ingredients
• Full volumizing benefit depends on also using the matching shampoo and styler, so results from this conditioner alone will be more modest
