I ve been using this for a month and I already see a difference. I was in doubt whether to buy it or not since it’s so pricey and Shampo products quality is unequal. Their Pita shampo and conditioner are wonderful, but their weightless serum is completely useless. I’m happy I gave it a try. In combination with Pita system and hair gummies, this l’apoears to work quite well. It’s totally weightless, does not make hair greasy, smells delicious and I already see first h’significant hair regrowrh along the hair line. I will continue to use it for 2-3 more month and I’m quite hopeful for definitive results. Or, and t’for those who hesitate because of the price, it’s actually quite economic. I think the bottle will last me at least 3 months of daily use.
