DALLAS Biotin Thickening Shampoo – Volumizing & Strengthening Hair Cleanser, All Hair Types

My wife purchases this product many times and it thickens and nourishes her hair, which looks beautiful at 75 years old.

After 24 years of using whatever shampoo and conditioner my mother bought, I realized I’m definitely using products way too heavy for my fine hair. I did a lot of online research and found that this was one of the most recommended shampoos for fine hair. So far, I love it. I’ve used it a few weeks now and my hair seems so light and bouncy. The smell is good, not as strong and yummy as my old Bed Head shampoo and conditioner but it’s definitely not a bad smell. Since I cut my hair about collar bone length, all I use is this shampoo, no conditioner, and no more oil for my ends and things have been GREAT. Now, the poor reviews do hold weight so here’s why this shampoo might not be for you. People were complaining that it takes a lot of shampoo to get it sudsy and clean their hair and here’s how I found this is true. On a normal day, it takes me less than a quarter amount and it suds up just fine and cleans my hair great. BUT last week I curled my hair, used a texture spray, and wore it for two days applying more texture spray in between. When I went to wash it, it did not clean my hair. I woke up to greasy oily hair. So here’s the thing, if you have longer hair or use hair products on the daily, then no this shampoo is probably not worth it. You will need a large amount to clean your hair. If you’re like me, if you have short hair that’s usually always free from products, you’ll be just fine and your hair will look and feel amazing!

This thickening shampoo is amazing and smells wonderful. It makes your hair so clean, thick, and lustrous. Yes, it's expensive, but you only need a quarter size in your hand to get a full use. Lathers easily and fills the whole bathroom with a beautiful scent. It makes my hair shiny and bouncy. My hair stays clean and full-looking for up to three days. I was really surprised with how long it actually keeps my hair feeling super clean and super thick. I am excited to try the thickening conditioner, as well as, other products from R+Co. The way I found out about this shampoo line is from a sample pack of thickening shampoo and conditioner that I received 'free' with some perfume samples from a department store in Las Vegas. I was traveling and thought I would try out the sample pack and was blown away with the super high quality so when I got back from vacation, I made sure to search Amazon and found this wonderful full size 8.5 oz bottle. I ordered it through my Prime account with free shipping. I REALLY love this shampoo and encourage others to not think twice about the price. Get your hands on this stellar product; you will be a customer for life.

This product smells nice and leaves hair feeling very clean and conditioned. It is easy to use but is on the expensive side for the size.

This product works great! Has brought my hair to life, thick and full

Love the volume and scent

It smells nice and lathers well. A little goes a long way. I don’t think it does anything for strengthening or lengthening, so I’d probably opt for something cheaper or more effective.

Worth the price. Huge difference in the thickness of my very fine hair when I use this shampoo.

Pflegendes Shampoo, das feinem Haar tolles Volumen und Glanz verleiht, ohne zu beschweren.

Certainly gives the volume that I need

Great

I love my R&Co shampoo. My hair has thinned out significantly in recent years, and this biotin thickening shampoo has done wonders for the health of my hair. My hair feels clean and light. The product doesn’t weigh my hair down whatsoever.

Good.
