What the treatment does
Keratin smoothing at Xxenial reduces frizz, increases shine, and makes hair more manageable for daily styling. Clients often experience these improvements for up to 3 months, depending on hair type and care. The treatment’s effect varies by texture and previous chemical processing, so stylist assessment shapes realistic expectations rather than guarantees.
We tailor each keratin application to your specific hair; length, porosity, and history of color or chemical services influence outcomes. Your stylist evaluates these factors during a consultation and explains realistic expectations and upkeep. Because every head of hair is different, a final recommendation and the exact price are provided during your appointment.
What to expect during appointment
Your appointment includes an in-chair consultation followed by the smoothing service and styling; plan on 200 minutes from start to finish. A standard starting price is $300, but the exact quote depends on hair length and condition. We provide the final price during your appointment so you leave with a clear plan and cost.
Xxenial Hair Studio sits in San Francisco’s Mission District, steps from 16th Street Mission BART and Valencia Street’s dining corridor, which makes scheduling around commutes simple. We offer early evening and weekend openings to accommodate tech professionals, parents, and shift workers who need appointments outside standard work hours.
Aftercare and styling tips
Aftercare plays a large role in how long results last; following your stylist’s at-home guidance helps maintain smoothness and shine. Results can last up to 3 months but will depend on washing frequency, product choices, and how hair is styled day-to-day. Your stylist will explain maintenance steps specific to your hair during the appointment.
A keratin treatment commonly simplifies daily styling, reducing time spent blow-drying or managing frizz, though individual experiences vary. Follow-up touch-ups and routine trims extend the look and manageability; your stylist can recommend timing based on your lifestyle and commute patterns in San Francisco’s coastal climate.
