| Title: | Screening of candidates for biological hair care activity |
| Abstract: | The invention concerns a procedure for testing a potentially-active substance used in the hair-care field, this procedure being characterized by the fact that a fragment of at least one hair follicle without dermal papilla is isolated, this fragment being taken from beneath the point of attachment of the sebaceous gland and excluding the portion of the hair shaft located above the point of attachment of the sebaceous gland; that this fragment is incubated in a suitable culture medium for a sufficient period; that this fragment is placed in contact with a potentially-active hair-care substance; that a marker of the activity of said tested substance is quantitatively determined; and that the results of this determination are assessed as they compare to a control. |
