- Example 1 Action of the BSW on the pigmentation of the whole hair follicle in vitro
- the cytotoxicity of BSW was determined on in vitro melanocyte culture. As shown in FIG. 1, the LDH signal, a reflection of membrane damage and / or cytotoxicity, is observed in the presence of BSW at the concentration of 1 mg / ml and slightly in the presence of BSW at the concentration of 0.5 mg / ml. This signal completely disappears in the presence of BSW at a concentration of 0.1 mg / ml.
- the choice for the study of hair follicle pigmentation is therefore to use BSW at a concentration of 0.1 mg / ml.
- forskolin is used at a concentration of 1 ⁇ M.
- human hair follicles from volunteer donors who have undergone surgery, are harvested according to a dissection method described in L'Oréal patent FR 2 736 721. They are then placed individually in a survival medium of defined composition. To each follicle is added a defined amount of either survival medium or forskolin or an aqueous extract of BSW. The radioactive tracer of pigmentation is then introduced into the survival medium.
- Potential tracers are described by Larsson BS in Melanoma Res., 1991, 1 (2): 85-90. 2-thiouracil [ 14 C] was chosen in our case.
- each follicle undergoes after washing a total lysis by immersion in soluene-350, for 1 h 15 to 1 h 30, at 50 ° C.
- Each lysate is then introduced into a volume of scintillating liquid and the activity is measured after stirring for 10 to 15 minutes.
- the reading of the activity which depends on the incorporation of thiouracil [ 14 C] is carried out using the TRILUX 1450 Micro-Beta device. Since this activity is correlated with the amount of neo-synthesized melanin, this method can be applied to the study of the effect of a compound on the pigmentation of the hair.
- BSW has a very strong positive effect on the incorporation of thiouracil [ 14 C] into a human hair follicle model in vitro survival, after 5 and 4 days of incubation, respectively.
- Statistical analyzes are performed using the Poisson's law.
- Example 2 Effect of BSW, a C-glycoside derivative, and the combination of the two, on the growth of the entire hair follicle in vitro
- human hair follicles from volunteer donors having undergone surgery, are harvested according to a dissection method described in L'Oréal patent FR 2 736 721. They are then placed individually in a survival medium of defined composition (Williams E medium supplemented with glutamine, insulin (10 ⁇ g / ml), hydrocortisone and antibiotic).
- a survival medium of defined composition
- BSW survival medium
- C-glycoside derivative a C-glycoside derivative
- a mixture of BSW and a C-glycoside derivative a C-glycoside derivative
- the lengthening of each of the follicles is noted and mean elongation curves are plotted.
- the lengthening of the hair follicles in the presence of BSW, a C-glycoside derivative, or the combination of the two, is compared to that of the hair follicles of the control group.
- FIG. 4 very clearly illustrates the synergistic effect on the growth of the entire hair follicle in vitro, which exists between, on the one hand, a hair growth promoting active agent such as C- ⁇ -D-xylopyranoside-2-hydroxy-propane and on the other hand, an excerpt from BSW.
- C- ⁇ -D-xylopyranoside-2-hydroxy-propane is used at the concentration of 2 mM and the BSW extract is used at the concentration of 0.02 or 0.1 mg / ml.
- an active promoting or maintaining hair growth such as a C-glycoside derivative allows a strengthening of the hair coloring effects of BSW by a synergistic effect exerted on the growth parameter.
- Example 3 shows different formulations of compositions for administering the product according to the invention.
- composition comprising both the BSW and the active promoting or maintaining hair growth. Such a composition is intended only for topical application.
