My friend's barber shop wants to raise the price of haircut and hair dyeing because the rent and water and electricity are rising. Need to write a customer notice, please help find a model.

I suggest you tell your friends that it is best not to adjust the price of haircuts, because hair salons don't make money by cutting hair. Your problem should be that there are more old customers, so you can't increase your haircut. If the price of haircuts goes up, there is a risk of losing old customers.

Your friend can replace some products before the price increase, and the same price as the previous products will do. Customer information can be written as (in order to improve the dyeing effect, some products in our shop are updated and the price of hairdressing items is slightly adjusted. Please understand. )
