Having battled hair thinning for quite some time, I was initially skeptical about trying RIAH’s Protein Shampoo. The first use itself left an impression – it lathers beautifully and has a gentle scent reminiscent of fresh rain in the countryside. After using this shampoo consistently over the past few weeks here in Toronto, I’ve noted not just less shedding but noticeable volume as well. It’s commendable that they have infused such varied proteins alongside peptides and caffeine which appear to foster healthier scalp conditions too! Even with my sensitive skin tone on high alert for irritations due to pollution levels around Lake Ontario, I found nothing troublesome; rather just comforting nourishment shining through those lovely locks.

After using the RIAH Shampoo for a month, my hair feels invigorated and more robust. The fine fragrance is like whispering winds from Oregon pine forests, it’s simply refreshing.

Wauw, deze RIAH shampoo is echt iets anders! Na een paar weken gebruik voelt mijn haar weer voller aan. De textuur van de shampoo is super romig en ik merk dat het helpt om die roos te verminderen door die zinkpyrithione – nog nooit eerder gehoord, maar het doet wat beloofd wordt. Plus, je krijgt ook alle proteïnen binnen voor zowel je hoofdhuid als haar; wie wil er nu niet sterk haar? Lekker geurend ook trouwens, niet te zwaar of chemisch!

Depuis que j’ai commencé à utiliser le shampooing RIAH Hair Loss Relief Pro R-tein, je sens une différence notable dans la texture de mes cheveux. Non seulement ma chevelure semble plus épaisse, mais ma peau capillaire se révèle également revitalisée grâce à l’ajout de protéines et d’acides aminés spécifiques. La formule équilibrée permet même un soin doux tout en maintenant une hydratation adéquate – fini les démangeaisons! J’apprécie particulièrement son pH faible qui contribue vraiment à améliorer mon cuir chevelu sensible après des saisons rudes ici en France.

I’ve been using RIAH Hair Loss Relief Pro R-tein Protein Shampoo for a month, and I love it. The shampoo is sulfate surfactant free, which makes it gentle on my scalp while still cleaning effectively. I appreciate that it contains zinc pyrithione; I’ve noticed less itching and irritation since I started using this product. The inclusion of 7 types of protein and 17 amino acids feels like it’s really nourishing my hair as well—it’s much stronger than before! Overall, I’m experiencing an improvement in my hair density and health.
