Private Label Hair Serum: buyer FAQ
Product-specific starting points for the first brief. Final answers depend on the selected formula, pack and destination market.
What is the difference between serum and leave-in?
A hair serum is an oil or silicone fluid for shine and frizz. A leave-in conditioner is a light cream or spray that detangles and moisturizes.
Can you claim heat protection?
Yes, if supported by a heat-protection test on hair. We arrange testing or keep the claim out.
Silicone-free possible?
Yes, using plant oils and alternative film formers. The finish will differ.
Which format sells in salons?
Sprays and serums in 100–150 ml are common salon retail sizes.
Will it make hair greasy?
We test on hair tresses and adjust oil levels for the target hair type.
What are the EU silicone rules?
Some cyclic siloxanes (D4, D5, D6) are restricted; we check the current rules for your product.
