Rida Hair Research Institute Anti Dandruff Deep Conditioner is a tea tree oil and 2% salicylic acid treatment that soothes flaky, itchy scalps while restoring moisture and improving scalp balance.
This deep conditioner is formulated to target visible dandruff and scalp irritation without sulfates or parabens. It pairs natural tea tree oil with a clinical-strength 2% salicylic acid exfoliant to loosen flakes and reduce buildup, while conditioning agents rehydrate the scalp and hair shaft. The result is calmer skin on the head, softer hair, and a cleaner-feeling scalp that is better prepared for daily styling and ongoing care.
Salicylic acid gently exfoliates the scalp surface to lift dead skin and debris, while tea tree oil delivers soothing, clarifying botanicals. Together they address visible flaking and the sensations that often come with an irritated scalp without stripping natural oils.
The conditioner contains antifungal-supportive ingredients and anti-irritant components designed to reduce the environment where scalp irritation and follicular irritation can persist. It is intended as a topical supportive product to improve scalp comfort and reduce visible buildup when used as directed.
After shampooing, apply a generous amount to the scalp and mid-lengths, massaging gently to ensure contact with flaky areas. Leave in for 3–5 minutes to let salicylic acid and tea tree oil work, then rinse thoroughly; use as needed or as part of your weekly regimen.
The formula is designed to both treat the scalp and nourish hair fibers, leaving strands softer and more manageable without heavy residue. It conditions the hair cuticle so you can style as usual and benefit from reduced flaking and better overall scalp health.
Who this is for: This deep conditioner suits people dealing with visible dandruff, occasional or persistent scalp itch, or those seeking an anti-dandruff treatment that also conditions hair. It is formulated for all hair types and is especially useful for anyone who prefers products without sulfates or parabens and wants a combined exfoliating and moisturizing step in their scalp-care routine. If you have a severe scalp condition or are under dermatologic care, consult your provider before adding new active products.
