Smoothing frizzy hair provides a sense of control, even if you live on the rim of an active volcano. Get explosive good looks with this voucher. Choose Between Two Options $81 for a keratin hair-straightening treatment (a $150 value) $204 for a Japanese hair-straightening treatment (a $400 value) Keratin smoothing treatments infuse keratin into hair cuticles, eliminating frizz, boosting shine, and rendering strands silky smooth for three to four months. Japanese straightening—also known as thermal reconditioning—achieves the same effects, but permanently, and is ideal for women with tight, unruly curls. Occasional touch-ups are required to treat new growth from the scalp. Some hair-straightening products that claim to be formaldehyde-free include aldehyde compounds, which are similar to the carcinogen formaldehyde. Side effects may include nosebleeds, headaches, vomiting, and respiratory problems, among others. Learn more about the health risks here.
