How T/Sal clears buildup

T/Sal uses 3% salicylic acid, the maximum over the counter strength. Salicylic acid dissolves the bonds between dead skin cells. Crusty scales lift away instead of sticking. The formula is free of added fragrance, color, and preservatives. A conditioning base keeps hair from feeling stripped. It starts clearing buildup after one use. The effect continues for hours after rinsing. This makes it ideal for thick, stubborn scaling. Regular shampoos cannot match this exfoliating power. Salicylic acid dissolves scaly buildup. It breaks the bonds between dead cells. Flakes lift away easily. The scalp feels cleaner fast. It also unclogs follicles. Clear follicles grow better hair. T/Sal uses a therapeutic level. Drugstore scrubs are weaker. Use it two to three times weekly. Alternate with gentle shampoo. Do not overdo the acid.

T/Sal vs T/Sal Plus

Classic T/Sal focuses purely on buildup removal. The Plus version adds piroctone olamine for yeast control. It also includes vitamin E and pro vitamin B5 for hydration. Plus suits people who get both buildup and recurring flakes. Classic suits pure scaling without much yeast activity. Both use the same 3% salicylic acid base. Plus costs a bit more per ounce. Pick classic for simple scaling, Plus for combo concerns. Plus adds extra moisturizers. It suits dry scalps better. Classic suits oily scalps. Both clear buildup well. The acid level matches. Only the base differs. Pick by your scalp type. Dry and flaky means Plus. Oily and flaky means Classic. You can alternate both. Seasons may change your pick. Winter dryness favors Plus. Summer oil favors Classic.

Using salicylic acid safely

Apply to wet hair and massage into the scalp. Leave it on for several minutes before rinsing. This contact time lets the acid work. Use it at least twice a week for control. Do not use it on broken or irritated skin. Stop if stinging lasts beyond the wash. Avoid contact with eyes completely. Keep it away from children. Follow with conditioner on the lengths. Acid needs respect, not fear. Follow the label exactly. Do not use daily. Two to three times weekly is enough. Rinse very well after. Residue can irritate. Keep it away from eyes. Stop if burning starts. Mild tingle is normal. Moisturize after each use. Dryness means cut back. Patch test sensitive skin. Read warnings before first use.

What results to expect

Crusty buildup softens after the first wash. Flakes reduce noticeably within two weeks. Itch eases as scales clear. Hair feels cleaner at the roots. Some dryness is normal at first.
