#1
Best Overall Alternative
- Size: 133.1 ml
- Price per ml: $0.06/ml (original $0.08/ml)
The why
A 3% salicylic acid treatment shampoo loosens stubborn scalp buildup and helps itchy, oily flakes. It suits occasional, targeted washing, especially alongside a rotation, but frequent use can leave curls, lengths, and already-dry scalps stripped.
One minus
Strips natural oils, so curly hair often needs a mask or cowash
Both recommended for Dandruff & Scalp Health; discussed alongside Nizoral A-D Anti-Dandruff Shampoo in 16 threads.
“Same brand as T-gel but the active ingredient is salicylic acid, which does help some forms of dandruff.”

Medicated Antidandruff Shampoo
Selsun Blue·Shampoo
See alternatives1% selenium sulfide; visible relief within one to several washes
- Size: 325.3 ml
- Price per ml: $0.02/ml (original $0.08/ml)
The why
A 1% selenium sulfide medicated shampoo for recurring dandruff, seborrheic dermatitis, and itchy scalps. It suits people needing a twice-weekly treatment rather than daily cleansing, though menthol, fragrance, and strong surfactants can leave hair brittle, frizzy, or irritated.
One minus
Dries scalp and hair; curls turn frizzy and lose definition

“Finally went to the dermatologist and now he uses selsun blue twice a week for 10 minutes at a time and his dandruff is completely gone.”

Best for Dandruff & Scalp Health
- Size: 499.8 ml
- Price per ml: $0.06/ml (original $0.08/ml)
The why
A strongly cleansing tea tree oil shampoo with a cold menthol tingle, aimed at flaky, itchy scalps and occasional buildup. It can calm symptoms for days, yet frequent use leaves hair and scalp dry, irritated, or itchier.
One minus
Very drying on hair and scalp
Both recommended for Dandruff & Scalp Health; discussed alongside Nizoral A-D Anti-Dandruff Shampoo in 12 threads.
“I have had crazy dandruff on and off my entire life, the only thing I have found that calms the itching and reduces flakes is the Paul Mitchell tea tree shampoo.”
