| Concentration note | 10 percent is high. Most published benefit occurs at 4 to 5 percent, and above that the main change is more irritation, not more effect | not published |
| Cost per wash | not published | 250 ml is roughly 25 washes |

| Patch test | Recommended, given the concentration | not published |
| Sulfate free | not published | Yes |
| Texture | Water-light, slightly tacky as it dries | not published |
| The vitamin C myth | Niacinamide and vitamin C were long said to cancel out. That came from a 1960s study at high heat and does not apply to modern formulations at skin temperature | not published |
| Usage | not published | It is a shampoo, not a treatment. The No.3 treatment is the concentrated product |
| What it does not do | not published | Nothing for split ends, which are mechanical damage and can only be cut |
| Who needs it | not published | Chemically treated hair -- bleached, coloured or permed. Virgin hair has few broken bonds to repair |
| Who reacts | A significant minority get flushing or stinging at 10 percent. Starting at 5 percent and building up avoids it | not published |
| Zinc PCA | 1 percent, included for oil regulation rather than for the niacinamide effect | not published |
