Hair growth cycle related parameters (anagen/telogen hair), hair pull test, hair shaft mechanical properties (hair elongation at break) and hair growth were assessed at baseline and after 56 (D56) and/or 84 (D84) days of products use. These parameters were completed by the subject’s self-assessment.Results: Telogen hair density was decreased by up to 26.9% and 24.2% while anagen density was increased by up to 10.3% and 10.8%, for WPLC–O and WPLC–P, respectively. These effects were significant compared with the placebo as early as within 56 days. These variations corresponded to an increase in the anagen/telogen ratio by up to 62.2% and 53.3% for WPLC–O and WPLC–P, respectively. Hair growth was also significantly increased in both active groups. At the end of the study the pull test was negative for aTE, exclusively in active treatment arms.Conclusion: Our findings demonstrated the efficacy of WPLC in both form in reducing hair shedding and in improving hair growth in women with aTE.Keywords: hair shedding, acute telogen effluvium, sphingolipids, digalactosyl diglycerides, nutricosmetics
