Réponse courte

To evaluate private label hair care samples, test each formula on strands and real models, score results with the same criteria, and involve the professionals who will use or sell it. Check smoothing, shine, scent, rinse and durability over several washes. Eco Beauty's Formula Discovery Kit brings 10 formulas for USD 129, fully credited on your first production order.

Points clés à retenir
  • Always start with a strand test before a full application.
  • Score every sample with the same criteria and the same hair types.
  • Involve two or three stylists, not only the brand owner.
  • Check results after several washes, not only on day one.
  • Use the results to brief adjustments before the first order.

Set up a fair test

  • Use the same hair types you will sell to (fine, thick, coloured, curly).
  • Follow the manufacturer's protocol exactly: time, rinse and flat-iron settings.
  • Photograph before, right after and after 5 and 10 washes.
  • Test one variable at a time when comparing formulas.

Which formulas to include in your test

Pick formulas for your hero service and its maintenance: for example a nanoplasty, a Brazilian protein, a pre-treatment shampoo and a mask. You can choose the same formula more than once, or include one custom formula request. See the options for Brazilian Keratin et nanoplastia.

From test results to first order

Share your scores with the manufacturer. Adjustments to fragrance or texture are made before the pilot, and custom formulas take 1-2 weeks of development for samples. Then confirm the production order from 300 litres per SKU.

How much does the sample kit cost?

USD 129 for 10 formulas, with free international shipping.

Is the sample cost refunded?

It is 100% credited on your first production order placed within 90 days of paying for the kit.

Can I request a custom formula in the kit?

Yes. A custom formula takes one of the 10 places and 1-2 weeks of development.
