Salvatore Tanino Therapy Curl Transition Kit MBFNO (3500ml) is the five-step Curls system that brings the natural curl and wave back and speeds the transition. Its Step B plant tannin, applied in the salon and carrying no formaldehyde, is built on collagen. Around it work Step M, the wash, Step N, the mask, Step O, the leave-in, and a Step F chemical-control mask.

Why this box
When a client grows out a relaxer, a keratin or years of hot tools, the head carries two textures at once. The natural curl comes in at the root, while dead, straighter lengths below will not fall into a pattern. That in-between phase is the transition, and it usually drags on for months of mismatched hair. This box is built to shorten it. The salon tannin step works the fibre so the two textures behave as one, and the home routine feeds the curl. We would reach for it the day a client decides they are done chasing straight and want their own curl back. Made in Brazil at Salvatore's plant in Presidente Prudente.
What is in the kit
Five steps, each with a job. Step B is the plant-tannin reset, the salon step that works the fibre so a two-texture head reads even; it is applied by the professional and carries no formaldehyde. Step M is a gentle collagen wash that cleans without stripping and readies the fibre. Step F is the chemical-control step that rebalances the hair's pH after the tannin or any colour and relaxer grow-out. Step N lays a biocollagen film that fills the gaps in worn lengths so the curl can hold water. Step O is the leave-in, built on collagen and D-panthenol, that gives the curl its spring-back and daily definition.
What to expect
The transition is a journey, not one appointment, and over it the two textures even out while the curl springs back stronger and frizz settles. The salon tannin does the structural work on the fibre, the biocollagen mask keeps the worn lengths drinking water, and the leave-in shapes the pattern day to day. We would say the honest promise is a shorter, tidier grow-out with a defined curl at the end, not an overnight change.
Who it is for
- Clients growing out a relaxer, a keratin or heat damage who want their natural curl back
- Curly, wavy and coily heads stuck between two textures through the grow-out
- Salons that run a curl-transition service and want the client's home care in the same box
Who it is not for
- Anyone after straightening; that is the smoothing kits, a separate service
- A client who avoids animal-derived ingredients, since the collagen here is animal-sourced
- Home use of the tannin; Step B is a professional step, not a shower one
Professional tip
The result you deliver on the day is only half the job; the transition is won between visits, and the miss we see most is a client who takes home nothing. We would run the tannin, then send them out with the wash, the mask and the leave-in and a clear routine, because the curl that keeps being fed is the one that comes back. Keep the leave-in off your roots, so the pattern falls clean instead of sitting flat and greasy at the crown.
How to use
Two parts: a professional service in the salon, then a home routine the client keeps up over the transition. In the salon you wash with Step M, work in the Step B tannin as Salvatore's curl protocol directs, and finish with Step F to rebalance the pH. Only trained hands run Step B, and the in-box leaflet sets its exact timing.
At home the client runs the lighter steps on wash day, so treat your mid-lengths and ends before the roots and let each step do its part. Repeat the wash, the mask and the leave-in as often as the curl needs through the grow-out.
- Wash with Step M. Cleanse the hair and rinse, because the tannin and the masks all take more evenly on a clean fibre.
- Work in Step B (salon). Apply the plant tannin as the curl protocol directs, so a two-texture head starts to read as one.
- Balance with Step F (salon). Use the chemical-control step as its pack directs after the tannin, so the fibre's pH settles before the client leaves.
- Feed with Step N (home). Comb the mask through the lengths and leave it twenty to thirty minutes, so the worn hair drinks the moisture up, then rinse.
- Finish with Step O (home). Work the leave-in through damp hair and skip your roots, so the curl springs back and holds through the day.
External use only. Avoid the eyes and rinse with running water if contact happens. Keep the bottles closed, below 40 degrees and out of sunlight, and out of reach of children and pets. Declared fragrance allergens differ between the five steps, and the tannin, Step F and Step O lists sit on their own packs; check each one before use. If any abnormal reaction occurs, stop and seek advice. See each pack for the full ingredient list, and follow the professional protocol for Step B.
Where it fits in the range
MBFNO is the curl-transition box, the one for a client moving back to their natural pattern. When the curl is already home and just wants feeding, the MNO system does that alone; smoothing sits in the A and B kits, a separate service. Which letter step does what across the range, and which kit is which protocol, is set out in our Tanino Therapy steps A to O guide. On curly and afro hair, whether you take it smooth, softer or define the curl is set out in our Tanino Therapy on curly and afro hair guide. The rest of the line sits under Salvatore Tanino Therapy.

Frequently asked questions
What is the MBFNO kit for?
It shortens the grow-out when someone moves from chemically-straightened or heat-tired hair back to their own curl. The salon handles the tannin; the home steps keep the curl fed while it comes in.
How long does the transition take?
It depends on how much straightened or damaged length there is to grow out, so think months rather than one visit. The kit is there to make that stretch tidier and quicker, with a defined curl at the end.
Does it straighten the hair?
No. It coaxes the natural pattern back rather than taking it out. If a client wants straight, that is the tannin smoothing service in the A and B kits, a different box.
Does the tannin contain formaldehyde, or animal ingredients?
No formaldehyde goes into Step B. The collagen across the box is animal-sourced, though, so it does not suit anyone avoiding animal ingredients. The tannin, F and O lists are printed on their own packs.
How is Step B applied?
By the professional, following Salvatore's curl-transition protocol on the leaflet in the box; the exact timing and method belong to that protocol. It is not a home step, and the wash, mask and leave-in are the parts the client uses between visits.
