| Résumé : |
- Objective : Hair loss is a major source of psychological distress for affected people. Safe and natural ingredients are therefore needed to help reduce hair loss and stimulate hair growth. This pilot clinical study aimed at exploring the efficacy of a wheat polar lipid complex (WPLC, Ceramosidesâ„¢), containing sphingolipids and digalactosyl diglycerides, on hair characteristics improvement in women showing acute hair shedding.
- Methods : Sixty-six women presenting a proportion of hair in the telogen phase greater than 15% were recruited and allocated to two groups, each including at least 10 postmenopausal women. For 84 days, participants consumed 30 mg/day of the WPLC supplement, or the placebo. Their hair characteristics were assessed after 56 and 84 days using phototrichogram evaluations of hairs in anagen/telogen phases, measuring hair shedding by a pull test, hair diameter and elongation at break point, hair growth and scalp sebum content. Hair density and volume were also clinically evaluated. All these parameters were also investigated in the subgroup of postmenopausal women.
- Results : WPLC supplementation decreased telogen hair density/proportion while increasing the anagen hair density/proportion. These effects were significant compared with the placebo as early as within 56 days. It also led to reduced hair shedding upon pull test analyses. If no changes were evidenced in hair diameter, WPLC improved hair growth and resistance to breakage after 84 days. Clinical evaluations also showed hair density and volume improvement. Furthermore, supplementation decreased scalp sebum content in women with oily hair. The beneficial effects were also observed in the subgroup of postmenopausal women. Finally, WPLC supplementation improved participants' perception of their hair conditions.
- Conclusion : Through a reducing effect on hair shedding and a stimulating effect on hair reappearance and growth, WPLC dietary supplementation was shown to significantly reduce hair loss in women. |
