'Wow effect': Dove's new $7 biotin shampoo gives thinning hair a boost, fans say

One thing that creeps up on us as we age? Thinning hair. Our ponytails are suddenly much smaller, and the shower drain? Well, we don't have to mention that. But there are inexpensive ways to combat thinning hair — one of which is a new offering from Dove: Volume & Fullness Shampoo With Bio-Protein Care. You can get it at Amazon for just $7, a fraction of the price of other shampoos and supplements for thinning hair.

No matter how rebellious our hair gets, we like to pamper it so we can hang on to those long locks of our youth for as long as possible. But as the years pass, it's common to see a few extra strands swirling down the drain, leaving your crown feeling a tad sparse. This Dove shampoo aims to help with that. It's packed with proteins to cut down on breakage and keep your hair full, while ingredients like coconut oil condition and smooth strands and make your hair easier to comb through. It also contains biotin, a scalp-friendly ingredient that can support hair health.

More than 4,000 shoppers have added it to their carts in the last month, and the early reviews are promising.

"It lathers up nicely and has a slight scent that is fresh and not overpowering," shared a five-star fan. "I use the same matching conditioner and my thin hair styles better and shines a bit more than regular shampoo."

"This is my first experience with this particular Dove product and I am very happy I tried it," another reviewer wrote. "It leaves my hair super soft and manageable. It has bounce and fullness now and it smells great. I use both the shampoo and conditioner. I highly recommend it to those with thin/fine hair like me."

"I have an oily scalp and fine hair," lamented a shopper. "This shampoo is excellent — cleans my scalp well, doesn't make my hair or scalp dry, and provides noticeable volume."

"I had a wow effect on my hair the first time I used it," raved another fan. "It gave me all the volume. Beware that it is a very clarifying formula and can dry out [hair] if not using a leave-in conditioner."

Another shopper added: "I've noticed that it definitely dries out my scalp. My head is always itchy after I use it for too long. I like to change this out with a more hydrating shampoo every other time I use it."
