| Your Situation | What the product requires (official) | Risk signal from 1-3 star reviews | Condition you must meet |
|---|---|---|---|
| Fine or thin hair | 4.0 fl oz treatment | “Will not buy again. I rarely give a product three stars but I really did expect more from ” | if this matches your hair type, review the tradeoffs above before buying |
| Oily scalp / product buildup | 4.0 fl oz treatment | $9.00 per fl oz | if this matches your hair type, review the tradeoffs above before buying |
| Color-treated or bleached hair | 4.0 fl oz treatment | Hybrid formula — less repair depth than a mask | if this matches your hair type, review the tradeoffs above before buying |
| Dry, coarse or damaged strands | 4.0 fl oz treatment | Packaging change confused repeat buyers | if your ends are dry or porous, pair with a conditioner |
