Should I also take into account my personal lifestyle and hair care routine? Is it prudent to consult with a professional stylist who can offer tailored advice on the best regimen? Ultimately, how can I ascertain the ideal timing that not only enhances the aesthetic appeal of my hair but also ensures its long-term vitality?
