How Salicylic Acid Works
Salicylic acid is a beta hydroxy acid. It dissolves dead skin and oil. This clears flakes from the scalp. It also unclogs hair follicles. A clear scalp supports healthy hair.
3 Percent vs Gentle Formulas
T/Sal uses 3 percent salicylic acid. This strength treats heavy buildup. CLn uses a milder approach for daily use. Start with the stronger formula for flakes. Switch to gentle for maintenance.
Flakes vs Dandruff
Salicylic acid treats flaking and scaling. True dandruff may need antifungal ingredients. T/Sal targets scalp buildup specifically. See a dermatologist for stubborn issues. Correct diagnosis guides the product.
Frequency of Use
Use 2 to 3 times weekly for active flaking. Reduce to weekly once clear. Daily use can dry some scalps. CLn suits more frequent washing. Adjust to your scalp's response.
Conditioning After Treatment
Medicated shampoos can dry hair lengths. Always condition after use. Focus conditioner on mid-lengths and ends. Keep it off the freshly treated scalp. This balances treatment with moisture.
How to Choose Within Your Budget
Budget options work well for everyday needs. Mid-range products often deliver better ingredients and performance. Premium options suit those wanting the best formulas.
