Formulated for chemically damaged, weakened, or over-processed hair that needs extra protein reinforcement; the added silk, keratin, and oat protein target strands that have been through color, perm, or heat damage. It's a mainstream retail shampoo, not a professional-only, salon-mixed product, and suits any adult regardless of gender. Because AG has discontinued the line, it's best suited to existing users restocking a favorite rather than someone starting a new routine, since there's no guarantee of long-term availability.

The case for Tech Two comes down to protein load: at roughly double the protein of a standard shampoo, it's built to reinforce hair that's been weakened by chemical services or heat styling, rather than just adding shine. The salt-free base skips the drying effect some cleansers cause through sodium chloride thickening, and the herbal extract blend gives it a soothing quality beyond straight cleansing.

Massage into wet hair, work into a lather, and rinse. Repeat if your hair needs a second cleanse. Follow with a moisturizing conditioner suited to chemically treated hair.

Pros: a genuinely protein-heavy formula for a shampoo, which matters if the goal is reinforcing over-processed strands rather than just adding slip; salt-free, so it avoids the extra dryness that sodium-chloride-thickened shampoos can cause; includes a soothing herbal-extract blend rather than being cleanser-only.

Cons: it's a sulfate shampoo, so it's not a fit for anyone specifically avoiding SLS/ALS; AG has discontinued it, so once current stock sells out it won't be restocked; it contains added fragrance and a synthetic dye, worth noting for sensitive scalps.
