Number 4 Mini Hydrating Shampoo, Travel Size Shampoo for Women and Men. Sulfate, Gluten, & Paraben Free. Moisturizing & Color Protecting, 1.5 oz

I use the moisturizing shampoo, conditioner, leave in serum and thermal spray by this brand. Using then together my hair feels like feathers.....this is so lightweight. The serum was the real game changer it made my hair so luxurious. The bottles are small but very concentrated you dont need much at all. It doesn't lather like normal shampoos but it works better. Only a small amount is needed. You dont need to wear perfume because your hair will smell so amazing and it lasts

The scent is light, but amazing. Shampoo leaves my hair clean and soft for days. An absolute favorite!

Omg...I think I've finally found the perfect shampoo for my hair type (and I've went through a ton of them in my 46 years). Lets start with saying my thyroid caused my hair to start falling out and become frizzy/dry. My hair is color-treated and wavy. I flat-iron and wash my hair every other day and this stuff has seriously brought my hair back to life with several compliments..that I haven't had in a long time on my hair. Most the time I start out loving a hair product only to find it ends up with the rest of them, heading to the goodwill for one reason or another. I have been using this for over a year and will stray to try the next eye catching, magazine rated top products of the year (you would think I'd learn), only to come back to old faithful. The smell is heavenly and last all day into the next.

This is a rich, lathering shampoo that has a pleasant scent to it. My hair feels and manages so well after I use it. A friend shared a sample of both Number 4 L'eau de Mare Shampoo and the conditioner. There was enough of each for me to use it several times before I decided to buy both of them. I give it a strong endorsement.

Love how soft this shampoo makes my hair even when rinsing it out. I have dry, damaged hair from over proccessing, it really mosturizes it. It's concentrated and I don't need to use as much as other shampoos. My hair feels fuller also. It has a great woodsy scent.

Yes you will notice your hair is slinkier, but like most shampoos and romance, it wears off. It just doesn't perform as well. It helps to use a cheaper product once in a while to spice things up, like suave or Vo5. This strips the build up off for a clean slate. Only do this once a month or your hair will dry out. Previously I used Biolage before and loved it just as much as Number 4 and a fraction of the price. But they changed the ingredients after selling it to another company, and it's not quite the same. But so much cheaper than this product! I have admit, I would spend the $75 again (25 fl oz). It did last a year, I used it every three days gingerly and I have a lot of hair, and long.

I ended up using the entire bottle. I have been using this brand for 3 years. The one I received was either fake or a bad lot. Like others noted in their reviews, the color of the shampoo is a yellowish cream color, not the light pink color. The scent is also muskier than the “real” version. Consistency is a little thinner but not noticeably. All in all, the shampoo shampooed but long term I noticed that my hair was not hydrated like it had been and my scalp has become much oilier over time. I started using this brand because it actually reduced the oiliness of my scalp but it’s basically returned to the way it was before using this bottle.

I can't get enough of this shampoo! I got it as a sample when I was subscribed to Birchbox and fell in love with it's great smell and how well it cleans my hair. Amazon's price was waaaaay better than Birchbox. I ordered this back in October 2016 and I don't think I've even used half the bottle yet (It's March 2017 now)! I don't like fruity or sweet smelling shampoos, so this fulfills my wish for a more gender neutral scent. It is a super concentrated shampoo, so just be careful to not use too much in your hair or you'll get dandruff.
