Noticeably Stronger, Healthier Hair
I've been using Marc Anthony Strengthening Biotin Shampoo for at least a couple of weeks now, and I'm genuinely impressed with the results! From the first few washes, my hair started feeling stronger, healthier, and more resilient- a noticeable change compared to before. The shampoo has a nice, fresh scent that isn't too overpowering and it lathers well without stripping my hair. After rinsing, my hair already feels clean and soft, which is something I didn't get with other shampoos I've tried. Will continue use, I've noticed that my hair seems less prone to breakage and split ends. I appreciate that it doesn't leave my scalp feeling dry or irritated.

Just Left The Salon Feel
Leaves hair feeling like that “just left the salon” feel. After just one use my blonde highlighted, fine hair is smooth, yet manageable. The scent is nice and not overpowering too. Excited to try the other products in this line.

Helps with frizziness
I like this shampoo for my curly hair. It cleans well and definitely helps with frizziness. I have tried another curl shampoo and returned to using this one. My only complaint would be it smells ok....nothing special. I wish it had a stronger lasting scent but continue to use it because it's the best product for my curls.

Effect
Ran out of my usual Joico purple and figured I would give this a try. It was a recommendation after I purchased the “long and strong” mask (I think?) anyway, I have found that I like this Marc Anthony product far better than the Joico or Pravana that I usually switch between. I love the scent, I love how effective it is as keeping my blond icy, and it makes my hair super soft and feeling moisturized (I don’t generally use conditioner) unlike other shampoos that have left my hair feeling extremely dry. It was a $9.99 gamble that worked in my favor. 10/10.

Affordability, Cleans Hair, But Stronger or Faster Growth(?)
Okay, I will give this product 3 stars. One for affordability, one star for fast service (it did arrive quickly after I ordered it) and one star for cleaning hair. However, as for stronger or faster growth--ehhh. Hair, typically grows about an average of 1/2 inch a month (don't believe me check it out). You can't always make it grow faster. There are things that can hinder growth, though, like lots of bleaching or chemical processing of hair that might cause breakage or lots of heat styling without protection. Hair growth is mainly determined by genetics and diet. Make sure to eat a good diet that will nourish those hair follicles foods rich in proline, lysine, biotin and keratin (which is protein building block of hair). So, while this shampoo is sulfate-free it is probably in the same class as other sulfate-free shampoos--gentle on colored hair and less stripping of natural oils, but that is about it. Should you still want to try it you can find it at some Walmart stores sometimes. As for me I prefer the shampoo I was already using, eat a good diet, get regular trims to take care of split ends and use a natural boar bristle brush.

Great product
I really like this product. I have read some say they had hair loss I have not noticed that as a problem for myself. You only need a small amount and it lathers very well. I have very long hair and people are always saying how nice it appears.

I have been using this for 9 months, this is my second tube. I have really noticed that my hair is growing faster then normal and also has more body in it. Very pleased with results. Highly sceptical when I first tried it but it has made a noticeable difference. Very happy with product but not happy with the price increase of $6.70 from 20/07/22 $13.29 to 02/04/23 $19.99, which is a 33.5% increase????

I buy the Marc Anthony instantly thick hair products because they really do work well on fine hair. Using this brand of shampoo, conditioner and styling cream definitely gives fine hair more body and actually makes it look thicker. Fine hair has a tendency to fall flat even when using hairspray but with this stuff it doesn't and it also holds curls better too. I haven't noticed that it actually thickens hair but it does give the appearance of thicker hair, which I really appreciate.
