Straightening formula for salons. How to choose.

A straightening formula is not just another product on the shelf. It is the salon's good name. Here is what to check before a bottle goes on your station.

Six questions before you buy

1. Registration. A licence number from the Israeli Ministry of Health, in the right category. Without it, stop there.
2. Ingredients. No formaldehyde and no glyoxylic acid. Whoever works with the product every day breathes it every day.
3. A written protocol. Processing times and heat by hair type, strand test, finish. A product without a protocol is guesswork.
4. Training. Who teaches the team to work with the product, and what happens when a question comes up in the middle of a treatment.
5. A result you can show. Before and after at the same camera distance and in the same light, and clients who come back.
6. Price per treatment, not per bottle. A 1000 ml bottle used with the right protocol gives a known number of treatments. That is the number to compare.

One protein or two

Most products on the market rely on a single protein. It straightens or it softens, not both. Herboss straightening was developed with keratin and collagen in one formula: keratin builds the structure, collagen seals and softens. For the salon that means fewer corrections, fewer complaints about "straw hair", and clients who come back for their roots rather than going to another salon.

What training on the product looks like

Herboss straightening training is done on real hair, not on a mannequin head: diagnosis, strand test, processing times by hair type, heat, and finish. The team leaves with a written protocol and someone to contact when a question comes up mid-treatment. A salon that has completed training appears on the map of certified salons and receives clients we refer.

Questions for the supplier, before you sign

1. What the registration number is and what is on the ingredient list.
2. What the price per treatment is, not per bottle.
3. What the salon gets besides the bottle: training, protocol, support, clients.
4. What happens when a treatment does not come out as it should.
5. Who else works with the product, and whether you can see results.

Why it is not sold for home use

Because the result depends on controlled heat, precise processing times and trained hands. A product sold to anyone turns into complaints about the brand, and we share that good name with our salons.
