are extensions high maintenance?

the short answer is yes and no. lol

the yes part is exactly what you would expect.  every 6-8 weeks you need to have them moved up. but you are likely getting your color done on that schedule already. the other hight maintenance fact is wash day. on wash days once or twice a week, you will have to spend more time styling your extensions. 

but, 

after you spend this time on styling your hair, you wont have to spend more than a couple of minutes a day for the next few days. so, low maintenance on those days, at least 5 days a week. 

everything great takes time. styling your extensions is absolutely worth the extra effort to keep your hair great every day.
