Hair Mates NY
Located near Astor Place, this Japanese hair salon offers some really awesome service and cuts for reasonable prices. Their original price is about $30-$40, but if you call ahead, you can book an apprentice that will only cost about half of that! They mainly cater to the young and hip Asian community, so they are most familiar with straight hair. Check their website for their other locations in the city.

Baishi Beauty Salon
Men can get a cut for $8 and women won't run for more than $13. There are no appointments, just seven chairs, a collection of spray bottles and scissors. This isn't a high-end salon as you can imagine, but a good place to get rid of those rigid ends for a very reasonable price.
This salon is usually full of regulars, but no appointment is required. Men can get a high-quality cut for $30 and women for $35-$40. All cuts include a complimentary wash with Tigi Bedhead products and a scalp massage. Call ahead for a dry-cut if you don't want a blow-dry finish that may add on an extra $15.
