"Reduce hair loss by activating scalp functions". Now what is that even supposed to mean?!
There is nothing in the ingredient list that will help with hair loss, especially if it's genetic. There's also Sodium Laureth Sulfate which is a cheap and harsh cleansing detergent that's not very good for your skin. I personally wouldn't recommend anyone to use this shampoo if looking to treat hair loss.
If there's any shampoo that will actually do something to help, use one that contains an ingredient called Ketoconazole. It's an anti-fungal treatment with anti-androgenic and anti-inflammatory properties that can help improve the health of the scalp. Good shampoos to use for hair loss which contain Ketoconazole are Lipogaine Big 3 Shampoo, Regenepure DR, and Revita are really good ones to use, and are also free from sulfates. They cleanse your scalp nicely and provide a clean environment that's convenient for topical treatments as well.
