First of all, there is no such thing as "bad hair." Our Creator knew what He was doing when He created us.
Now, for people born with "low maintenance hair." You are blessed.
Low maintenance hair is hair that can be washed and air-dried or diffused. No wrapping at night. No rolling at night. No flat ironing. Just finger and go.
Low maintenance hair can have the flexibility of being worn straight which makes it high maintenance for that time period.
Now, for those who do not prefer to wear their curl pattern or if you don't have a curl pattern at all, our hair (me included) is high maintenance all the time.
High maintenance hair is sensitive to chemicals, heat, weather and stress. Finding a hairstylist is extremely hard. Most of the hairstylists with absolutely gorgeous hair are born with "low maintenance" hair.
Just because their hair looks gorgeous does not mean that they know how to maintain your higher maintenance hair.
If you are interviewing a hairstylist, ask about their maintenance for their hair. How often do they need a chemical touch-up? is a great question. If they are at 8 to 10 weeks, and you know you have an afro pushing 5 weeks, then you also know that your hair is not in the ballpark with their hair. I would keep looking for the next hairstylist in that case.
Now, suppose the hairstylist's hair looks a "hot mess?" Interview them anyway. Why? I always find it hard to work long hours and maintain a cute style with high maintenance hair. You either are going to pay "top dollar" to offset the fact that the stylist needs to keep her hair done . . . or you are going to let her work speak for itself.
As far as male hairstylists go, I do not understand how men keep their hair barbered short and female clients are drawn to them for service. Female hairstylists can not even get a break. Their hair has to look flawless all the time.
Good hair means low maintenance hair. Bad hair is good hair. It takes more time, but when you find the right stylist -- life is good! Keep interviewing until you find her!
