The Unove Deep Damage Repair Shampoo functions similarly to a clarifying shampoo but is milder, offering a gentle fruity-floral musk fragrance with hints of citrus and sweet berries. It effectively cleanses your hair and scalp, eliminating dirt and residue without leading to dryness, flakiness, or itchiness. My main concerns with my long, color-treated hair were split ends and breakage, but after just one use, I discovered that this shampoo fortifies damaged strands.

In summary, if your aim is to get a bright smile, niacinamide probably isn't the best choice.
