The shampoo does the cleansing with sodium laureth sulfate and cocamidopropyl betaine while leaving whey protein, biotin and hydrolyzed keratin behind on the fibre. The conditioner then takes over: its cetearyl alcohol and quat base coats the strand for easy detangling and its castor seed oil, shea butter and coconut oil seal in softness. Used in sequence, one step deposits the protein and the next locks in the emollience, which is why the line is sold as a pair.

Learn moreMeet the Retrô Cosméticos Super Tônico Strengthening Hair Kit – Kit of 2 (10.1 fl oz / 300 ml shampoo + 10.1 fl oz / 300 ml conditioner), the complete two-step ritual from the brand's green-and-gold Super Tônico line — and the only Retrô line that comes as a full wash-and-condition pair.
Both bottles run on the same system: biotin and whey protein, hydrolysed keratin, panthenol and Brazilian castor seed oil. The shampoo clears away oil, sweat and styling residue while depositing protein on the fibre; the conditioner follows with slip, softness and the emollience that fine, fragile hair needs to move freely instead of snapping.
Buying them together is also the way the brand intends the routine to be used — one product recommends the other on the label, and the kit price is lower than the two bottles bought separately.
Included in This Kit
- Super Tônico Strengthening Shampoo – 10.1 fl oz (300 ml): a well-lathering everyday wash with biotin, whey protein and hydrolysed keratin that cleanses the scalp and helps hair feel more resistant.
- Super Tônico Strengthening Conditioner – 10.1 fl oz (300 ml): a creamy rinse-off conditioner with castor seed oil, shea butter and coconut oil that detangles, softens and leaves lengths luminous.
Key Features:
- A complete two-step routine: wash and condition from the same line, formulated to be used one after the other.
- Biotin and whey protein: two of the best-known conditioning actives in strengthening haircare, in both bottles.
- Hydrolysed keratin: helps reinforce the appearance of weak, porous strands so hair feels more resistant.
- Brazilian castor seed oil: Ricinus Communis Seed Oil adds softness and body to fine, limp hair.
- Easier detangling: the conditioner's slip means less pulling and breakage when you comb wet hair.
- Better value than buying separately: the kit is priced as a bundle rather than as two individual bottles.
- PETA-approved brand: Retrô Cosméticos carries PETA's Global Animal Test Policy approval.
How To Use
- Wash: on wet hair, apply a generous portion of the Super Tônico shampoo and massage the scalp and lengths in vigorous circular movements. Reapply if needed, then rinse.
- Condition: with hair still wet, apply a small amount of the Super Tônico conditioner along the full length, coating the strands.
- Wait: give it a minute to spread from mid-lengths to ends.
- Rinse: rinse the hair delicately and completely, then style as usual.
Expert Tip: once a week, swap the conditioner step for the Retrô Cosméticos Alô, É Vera! Aloe Vera Rebuilding Hair Mask (10.6 oz / 300 g) — a deeper hydration break that pairs well with a protein-forward routine like Super Tônico.
Ingredients (Highlights)
- Biotin: vitamin B7, one of the most widely used conditioning vitamins in haircare formulas.
- Whey Protein: a milk-derived protein that helps improve the feel and body of fine, limp hair.
- Hydrolyzed Keratin: small keratin fragments that help reinforce the appearance of weakened, porous strands.
- Ricinus Communis (Castor) Seed Oil: a thick, glossy oil long used in Brazil to soften and add weight to fine hair.
- Butyrospermum Parkii (Shea) Butter: in the conditioner, a rich butter that helps hair feel supple rather than brittle.
