Is Elvital Fibralogy suitable for sensitive scalps or dry hair?

The shampoo contains strong sulfates and fragrance allergens, so it is generally better for normal to oily hair and may be too harsh for very sensitive scalps or extremely dry hair, which could benefit from a milder, sulfate-free formula. A patch test is recommended before regular use.

What role does Coco-Betaine play in this shampoo?

Coco-Betaine is an amphoteric surfactant that boosts foam, reduces the irritation potential of the harsher sulfates, and provides mild conditioning to help smooth the hair shaft.

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

For most hair types the product can be applied 2-3 times per week; it does contain methylchloroisothiazolinone and methylisothiazolinone, preservatives that are linked to allergic reactions in some individuals, so a patch test is advisable.
