I went for haircuts at Ouidad for about 8 years and now I go to Devachan (it's been another 8 years).
I much prefer Devachan - the salon, the haircut, the results, the products all wonderful! My Devachan haircut lasts 4-6 months so the cost is well worth it.
I go to the salon on Broome St - they start with a dry haircut, then take you to an upholstered lounge for your hair wash, conditioner, neck, head & shoulder massage. Then back out for styling products (love angell), clipping, and hair drying.
I can always count on my hair looking great when I leave the salon. The morning of my daughter's wedding she & I both went to Devachan salon. I got my regular haircut and was confident that it would look perfect for the wedding!
I just recently switched to a short, layered bob (after having medium length hair for years). With a haircut at a regular salon I would need a haircut every 6 weeks - it bushes out on the bottom. With Devachan, it still looks good up to 6 months later.
Good luck!
