Based on its formula, is this shampoo safe for sensitive scalps or dry hair?

The shampoo uses mild surfactants like Cocamidopropyl Betaine and Decyl Glucoside, which help reduce irritation, but the presence of Sodium Laureth Sulfate, fragrance, and synthetic dyes can still cause sensitivity in very delicate scalps; overall it is generally safe for normal to slightly dry hair but may not be ideal for highly sensitive or allergic users.

What role does Cocamidopropyl Betaine play in this shampoo?

Cocamidopropyl Betaine is an amphoteric surfactant that creates a gentle foam, improves the cleansing power of the primary surfactant (Sodium Laureth Sulfate) while reducing its harshness, and helps maintain hair softness.

How often should this shampoo be used, and does it contain any controversial ingredients?

It can be used daily or every other day for most hair types; however, it includes Sodium Laureth Sulfate and synthetic fragrance, both of which are sometimes highlighted as harsh or potentially irritating, and it also contains artificial colorants (CI 19140, CI 15985) that some consumers choose to avoid.
