Nioxin System 4 Scalp + Hair Conditioner 33.8 oz

Great product!

Before using Nioxin System 4 I noticed an increase in hair loss - not due to Covid. My colorist suggested that I try this product, explaining that hair loss can be associated with a scalp condition. I've used this for about a month and have noticed a significant difference. It's a great product. I repurchased and will continue to repurchase.
