Kristin Ess Deep Clean Clarifying Shampoo for Oily Hair & Build Up | Detox Purifying + Cleansing Oily Hair Treatment - Sulfate Free + Vegan - Product for Thick, Curly + Color Treated Hair

After years of dry scalp I had to buy a shampoo for very oily scalp due to Parkinson's Disease. This shampoo has a light scent and easily makes suds. It left my hair and scalp feeling really clean and shiny. I will buy again.
Shampoo Basics & Tips
Understanding Shampoo Efficacy for Specific Scalp Conditions
Parkinson's Disease and Scalp Health: Parkinson's can cause sebum overproduction due to autonomic nervous system dysfunction, leading to oily scalps. This explains why the user switched to a shampoo formulated for oily scalps despite previous dryness.
Key Features of Effective Shampoos
Sudsing Ability: The mention of "easily makes suds" refers to surfactants like sulfates or modern alternatives (e.g., glucosides) that remove excess oil without stripping moisture—critical for balancing oily scalps with dryness.
Scalp-Cleansing Mechanics
Clarifying Ingredients: Shampoos for oily scalps often contain salicylic acid or tea tree oil to unclog follicles. The "clean" feeling indicates thorough sebum removal while maintaining scalp pH (5.5-6.5) to prevent irritation.
Dry Scalp vs. Oily Scalp Paradox
Compatibility Factors: A shampoo addressing both dryness and oiliness likely uses humectants (e.g., glycerin) to hydrate dry areas and astringents (e.g., witch hazel) to regulate oil production—achieving the reported "shiny" yet non-greasy results.
Scent and User Experience
Fragrance Engineering: A "light scent" suggests phthalate-free perfumes or essential oils diluted to <1% concentration, avoiding sensory overload common in neurological conditions like Parkinson's.
