Hartill finest saloon is equipped with modern day amenities.is a clean air salon. When you walk in, it smells like … nothing. No products containing ammonia are used. If a client wants a keratin treatment or needs hair spray, it’s done in a “fume room” in the back, with its own ventilation. I did think it was interesting that they offer keratin straightening–Soho Organics refuses, only offering a formaldehyde-free relaxing treatment.
