  • Well worth it
Size: 25 Fl Oz (Pack of 1)
The only way I knew about this product is because a hairdresser from California relocated to my community in the Southeast. She turned me on to the whole line of products this company sells. I have never been disappointed. Yes, it's more expensive than your store bought stuff, but it lasts a long time and does not cause build-up in your hair. In my experience there's been no need to use a clarifying shampoo when using this product line. My friend has since moved back to California so I have been to several other stylists in the last year or two. I always tell them they need to make the switch to this product line. I color my hair often, the moisturizing shampoo and conditioner really do a great job on my hair. ... show more

  • I buy this for my boyfriend
Size: 8.5 Fl Oz (Pack of 1)
Amazing scent, and adds noticeable volume to hair. We got samples of the entire product line in a goody bag many years ago and my boyfriend loved this shampoo so much I had to track it down. Glad that Amazon carries it.

  • Brace yourself for aromatherapy and perfect hair!
Size: 8.5 Fl Oz (Pack of 1)
I've been alternating this shampoo with label M Honey and Oat Shampoo Label. M Organic Orange Blossom Shampoo - 33.8 oz / liter for a couple of years now and can say with confidence that I've struck gold! This shampoo is truly a luxurious experience. It was originally recommended to me be by my stylist and once again she did not fail. While pricey, just a few dime sized pumps (I have long, fine hair) lathers up into a fragrant pile of bubbles. I also use the Number 4. Volumizing Conditioner and will continue to use my hair beauty regimen until something better comes along.... though that a tall order to fill. ... show more

  • No. 4 is the best hair care anywhere!
Size: 8.5 Fl Oz (Pack of 1)
I originally received a sample of No. 4 shampoo in a beauty sample box I receive on a monthly basis. I immediately fell in love and became addicted to the fact that it got my hair incredibly clean without striping it. It leaves your hair baby soft and the smell is a very light floral but a clean one. I pair both the Fleurs de Temps shampoo and conditioner with the weekly hair masque and my hair has never looked better. Yes the price is a little more than what people consider acceptable for shampoo, however this is one of those items where a little goes a long way! ... show more

  • Cant really say bad because it IS shampoo. Just….Not what you think it is
Size: 1.5 Fl Oz (Pack of 1)
I bought sample just to have the good smell moment. Nope. Not the real deal, I would guess

  • My HG shampoo!
Size: 8.5 Fl Oz (Pack of 1)
This shampoo has been a staple for me for the past 6 years. I have seborrheic dermatitis, and this shampoo helps control itching and minimize oil production better than all the harsh medicated shampoos out there. The volume is a bonus. For everyone complaining that it isn't lathering or seems thinner or is counterfeit, try decanting into another container and shaking it up. I've put this shampoo into clear travel-sized containers before and noticed that it can separate. My guess is it can occur with temperature or pressure changes. When that happens, one half is super moisturizing, thin, and does not lather while the other half is drying and harsh. Shaking it up helps to redistribute it again. ... show more
