Keratin treatments typically last between 2 to 6 months, with the exact duration depending on factors such as the type of keratin treatment used, hair type, application method, and aftercare routine.
- Salon keratin treatments generally last from 3 to 6 months. These treatments are professionally applied and tend to have longer-lasting results, especially when proper maintenance is followed, such as washing hair only 2-3 times per week and using sulfate-free shampoos
- At-home keratin treatments usually last up to 3 months, as they are less intensive and often less durable than salon treatments
- There are variations in treatment strength and longevity: for example, an "Express Keratin" treatment may last 8-10 weeks, while a "Classic Keratin" treatment designed for coarse or unruly hair can last 4-6 months
- Proper aftercare, including limiting hair washing frequency and using gentle hair products, can help extend the life of the treatment. Some users report that regular reapplication can maintain the effects beyond six months
In summary, keratin treatments offer semi-permanent smoothing and frizz reduction effects lasting from about 2 months up to 6 months, with salon treatments on the longer end of that range and at-home treatments on the shorter end.
