This extensive Biologique Recherche hair care treatment is specifically blended to optimize the fortifying and revitalizing action at the root of the hair.
Apply about 5 ml of the serum to the whole head. Massage gently in circular movements. Do not rinse off. Use once a day for a 1 to 3 month period, or occasionally after shampooing
"What a great product to use on your wet hair after you wash and towel dry your hair. Not greasy no trace at all really but feels refreshing and after 2 weeks can tell my hair falling dropped to 50%! It does not have smell, you barely even know you used anything and the pump at the bottom to use the product is sooooo easy to use! Love it and will buy in 2-3 months again when I go through regular Spring shedding."
