2. Hair mask and baking oil are two completely different hair care concepts. Simply put, baking oil is a bit like make-up, which can quickly create a radiant makeup effect. After baking oil, you can immediately see the improvement of hair, but this improvement is short-term and superficial. After a period of time, with the influence of shampooing, sun exposure, pollution and so on, the hair will return to its original appearance. Unlike the hair mask, the hair mask is more like a night cream, which is a deep maintenance. The hair mask is rich in nutrients and moisture and can penetrate into the hair through the hair scales. Relatively speaking, the hair mask takes effect slowly, and it needs to be used for a period of time to see the effect, but it fundamentally changes the hair quality.
