Before modern hair treatments, frizzy hair could only be smoothed by pressing it with an iron or by running it through the fingers of a jazz pianist. Achieve a noteworthy 'do with today's Groupon: for $139, you get a Brazilian blowout or Brazilian Blowout Zero at European Flair Salon and Day Spa in Beaver (a $360 value).

European Flair, awarded the day spa Silver award by the Beaver County Times, stirs hospitality, technique, products and pristine facilities into a bouillabaisse of professional-salon services. Brazilian blowouts tame frazzled locks while simultaneously restoring sheen to strands fried by chemical treatments and renting head space out for cell-phone towers. The combination of nutrients and a proprietary polymer system form a protein sheath around tresses, smoothing the cuticle and conditioning the hair. Alternatively, Brazilian Blowout Zero eschews glycol and formaldehyde for a plant-derived bonding system to defrizz tresses and give scalps the ability to command armies of ferns. Additional aftercare and styling products to extend the life of blowouts not included. However, the Brazilian blowout can last up to 12 weeks with the use of aftercare product regimen.

Within the spa interior, floral arrangements offset tranquil white walls as clients catch sight of their pampered visages in antique framed mirrors. Between treatments guests can, like cat burglars that sneak into coffee shops after hours, sip on free coffee or tea.

Some Brazilian Blowout products include the carcinogen formaldehyde, which may cause nosebleeds, headaches, vomiting, and respiratory problems, among other side effects. Learn more about the health risks here.
