Dreaming of long hair often comes with the advice to visit the hairdresser regularly. But how can hair grow if the painstakingly cultivated lengths are constantly being trimmed? STYLEBOOK consulted Kim Fischer, a hairdresser at the salon “Kim & I,” for insights.
Overview
Healthy, long hair requires an elaborate beauty routine, which includes visiting the hairdresser–there’s no doubt about it, according to hair expert Kim Fischer in STYLEBOOK: “Proper care is definitely important. Regular trims, even if it sounds counterproductive, and using a soft brush. Also, minimize heat exposure and definitely don’t straighten every day.”
How often should I go to the hairdresser if I want long hair?
Hairdresser Kim Fischer: “Depending on hair quality, every eight to twelve weeks. This is very, very important! Split ends travel up. And if the ends are damaged and it travels up, you’ve lost. Then it’s a struggle to get a compact straight line at the bottom.”
If someone goes for regular trims, one centimeter is enough. Fischer: “You can achieve a good length in a year. Then it’s also a healthy length and not just dead tissue.”

Is hair texture crucial?
“The finer the hair, the more often it should be trimmed–even if you want it to grow. For thick hair, it’s enough to trim one centimeter every two and a half to three months,” says the expert.
Is it true that some hair only grows to a certain length?
The hairdresser clarifies that it’s usually due to improper care and not trimming often enough if hair stops growing. Fischer: “Many girls don’t go to the hairdresser often enough because they think their hair grows slowly anyway. Then you have to cut not just one centimeter, but five to six, because the ends are so damaged.”
However, Kim Fischer also knows cases where hair only reaches shoulder length, “but that’s really a small percentage of people. It often happens when the hair is very fine. If it doesn’t grow beyond a certain length, it could be due to a blood deficiency or a genetic predisposition.”

What else should be considered?
For hair to finally grow long, it requires a combination of good care, a healthy lifestyle, and patience. This starts with washing, as two to three times a week is completely sufficient. Use a mild, sulfate-free shampoo and always use a conditioner after washing to protect the lengths. Apply a deep-conditioning mask once a week (e.g., with keratin, proteins, or oils) for extra care.
What many women neglect is the scalp. A healthy scalp means healthier, faster-growing hair. Gently massage the scalp once or twice a week, e.g., with hair oil: rosemary oil or castor oil. Also good: scalp scrubs remove dead skin cells.
