If you want to learn hairdressing skills at the age of 45, I suggest you choose some professional hairdressing schools or hairdressing training institutions to study. Here are some ways to learn how to get a haircut:

1, beauty and hairdressing training institutions: There are many beauty and hairdressing training institutions on the market now, which generally provide comprehensive theoretical courses and practical operations, so that you can master hairdressing techniques systematically. You can search or consult relevant beauty salons or hair salons through the internet to learn about training institutions in this area.

2. Barber schools: In some cities, there may be some professional barber schools, which usually provide systematic theoretical and practical training, and may also include subjects related to the hairdressing industry, such as human anatomy, cosmetology, colorimetry and so on. You can learn about the relevant barber school information through inquiry.

3. Online learning: In the Internet age, you can also learn hairdressing techniques through online platforms, such as YouTube video tutorials. Although this method is relatively cheap and flexible, it needs to be screened and evaluated by itself to ensure that the learned content is reliable and practical. No matter which way you choose to learn hairdressing skills, I suggest you learn more about and compare the education level, curriculum, teaching staff, tuition and other factors of various learning methods and institutions in the process of choosing, and choose the most suitable learning method and institution on the premise of ensuring quality.
