The customer service at Beauty Care Brazil is exceptional, when ordering and receiving the products. I have used their website for ordering products twice, each with great success. Thank you. The hair straightening product itself is reliable and long-lasting, with beautifully smooth and manageable hair for around 3–4 months, depending on hair growth, before a touch-up is needed. The product contains keratin and is used on frizzy Caucasian hair (see photos).
