Overview
Applying a leave-in cream to the scalp is how this Nioxin leave-in treatment is meant to work, aimed at colored, dry and damaged hair with progressed thinning. The title credits niacinamide and biotin for nourishing the scalp and boosting hair density.
Built for hair that is both colored and thinning, and the leave-in cream format needs no rinse. The limits are the missing directions and no stated usage frequency. The title makes density and color claims that the listing does not support with measured results.
Who it's for
A person already using the Nioxin line who has color-treated, thinning hair and wants a leave-in step after washing. People looking for a rinse-off product or a fragrance-free option should look at other forms.
Pros and cons
- Leave-in cream needs no rinse
- Made for colored hair with thinning
- Niacinamide and biotin named
- Peppermint oil scent
- Usage frequency not stated
- Not a shampoo or conditioner
Performance notes
A leave-in cream stays on the scalp and hair after application, so the active ingredients have longer contact than a rinse-off product would give. The listing names nicotinate as the active and does not describe a regimen, so regular use as part of a full system is what the product line implies.
