The 2-Step Routine Set — S-7 Standard Shampoo + No.215 Leave-In Treatment

Two products, one routine — in the sizes you actually keep in the shower. This is how we use S-7 and No.215 in the salon: wash, then finish.

What's in the set

• S-7 Daily Shampoo — Standard Size (16 fl oz / 473 mL). The everyday bottle. If you wash daily, this is the size that lasts, at the lowest cost per wash.
• No.215 Leave-In Treatment Mist (4 fl oz / 118 mL). A water-free oil mist with a little more weight than No.115 — made for hair that is stiff, thick, or simply won't cooperate.

Step 1 — Wash with S-7

Apply to wet hair, massage into a lather, and rinse thoroughly. S-7 is a sulfate-free daily shampoo built around the reality of washing five to seven times a week, and formulated without cocamidopropyl betaine.

Step 2 — Finish with No.215, before you dry

Towel-dry, then spray No.215 generously through wet hair — root to ends, not just the ends. Wait about four minutes, then blow-dry and style.

The four minutes matter. Give the product a moment to settle through the hair before heat goes anywhere near it, rather than drying immediately after you spray. If your ends are especially dry, add a little more through the mid-lengths partway through drying.

On dry hair, for shine at the end of the day: use less, or spray once into your hands and work it through with your fingers.

Do you need a conditioner?

If your hair hasn't been color-treated, permed, or straightened, we don't think you need a rinse-out conditioner after S-7. Healthy, unprocessed hair usually has enough of its own cuticle intact that a rinse-out conditioner mostly adds weight — and it gets rinsed away a minute later anyway.

What we'd suggest instead is Step 2 above. A leave-in does its work where it actually matters: while you're applying heat, and for the rest of the day after.

If your hair is chemically treated, very long, coarse or tightly curled, or simply feels tangled after rinsing, keep your rinse-out conditioner. This isn't a rule — it's a starting point. No.215 sits comfortably alongside one.

Why No.215 in this set

No.215 is the richer of our two leave-ins. Same idea as No.115 — a water-free oil mist, no alcohol, no added fragrance — but with slightly more of the non-volatile silicone that stays behind, which is what gives it a more polished, more supple finish.

We reach for it when hair is thick, wiry, or too straight to fall the way someone wants it to, and when humidity is the real problem: hair that expands, loses its shape, and stops being predictable partway through the day.

It's also what we recommend before a flat iron, and as home care after a relaxer or a chemical straightening service.

If your hair is fine to normal, the No.115 version of this set is the better match.

Who this set is for

• Your hair is stiff, thick, or hard to control, and you wash it most days.
• Frizz and humidity are the recurring problem, not dryness alone.
• You've had straightening or a relaxer and want to hold that result at home.
• You already use No.215 and want the shampoo it was designed to sit alongside.

Trying it first

If you'd rather start smaller, the 2-Step Starter Set pairs the same No.215 with the 100 mL travel size of S-7.

A note on your shower floor

S-7 can leave a slippery film on shower floors and tubs. Clean the floor with soap after use — rinsing with water alone won't remove it, and the film becomes slippery again the next time the floor gets wet.

Caution

For external use only. May leave a slippery film — clean shower floors and tubs with soap after use. Avoid eye contact; rinse with water if contact occurs. Do not use on irritated or broken scalp. Discontinue use if redness, itching, or irritation occurs; consult a physician if irritation persists. Keep out of reach of children. Store in a cool, dry place away from sunlight and heat. Do not freeze.

⚠️ A note for your safety: No.215 contains organic Argan Oil. If you have a known nut allergy, please consult with a professional or perform a patch test before use. S-7 contains fragrance — a patch test is recommended for sensitive skin or allergies.
