Is this conditioner safe for sensitive scalp or dry hair?

The formula includes moisturizers like almond oil, glycerin and cocoa butter that benefit dry hair, but it also contains fragrance allergens (butylphenyl methylpropional, coumarin) and a formaldehyde-releasing preservative (diazolidinyl urea), which can cause irritation for very sensitive scalps; patch testing is recommended.

What does dimethicone do in this conditioner?

Dimethicone is a silicone polymer that forms a lightweight, water-repellent film on the hair shaft, reducing friction, preventing tangles, sealing in moisture and giving a glossy finish, which helps maintain color vibrancy and smoothness.

How often should I apply this conditioner, and are there any controversial ingredients I should be aware of?

For best results, use the conditioner 2-3 times per week or after each shampoo, applying it to wet hair and leaving it on for 1-2 minutes before rinsing; be aware that the product contains silicones, fragrance allergens, and diazolidinyl urea, a formaldehyde-releasing preservative, which some consumers prefer to avoid.
