Cons

•The blue bottle, which resembles the purple, did not provide the same thickening benefits and has a dish soap scent
•Can be expensive when not on sale
•Some users report that it dries out hair, leaving it brittle and frizzy
•Leaves hair feeling dry even with conditioner, requiring additional moisture masks
•Produces lots of foam, but suds do not necessarily mean better cleaning
•May strip natural oils excessively, especially for oily hair or those prone to dryness
•Some reviews mention that it does not effectively add volume for everyone or may leave hair feeling damaged
•The jellike consistency may feel unusual to some users

Bottom Line

This shampoo is a popular choice for fine and thinning hair, thanks to its biotin and collagen infusion that can boost volume and strength. However, it’s important to note that some users experience dryness and frizz, so if moisture retention is a priority, you might want to consider alternatives. If you’re after a sulfate-free formula with a pleasant scent that truly adds fullness without damage, this product is worth a try, but keep an eye on sales to get the best deal.
