i have used the lavender one and the green (?) one in shampoo and conditioner, would love to try the rose but can't afford it at the mo.
they are lovely to use and the scent is lasting and fresh, but to be honest i found i needed to wash hair more often.
made hair shiney, but then so does normal shamppo.
i could swear that alexis always claimed she used shea liquid soap on her hair, cos based on that theory i tend to wash once in fructis or whatever and the a 2nd wash in l'occitane shower gel, the vanilla or the amber give best shine, the condition with whatever pantene usually but then i squeeze suds over my hair from shower net thingie over my hair and rinse.
get good results
