To improve skin tone, consider topical creams containing active ingredients like Vitamin C, Niacinamide, or Retinol, and always use a broad-spectrum sunscreen daily. For an oily scalp, shampoos containing Salicylic Acid, Ketoconazole, or Zinc Pyrithione can effectively regulate excess oil. To address hair loss, topical Minoxidil is a well-established generic option that promotes hair regrowth. Since these concerns are very common and highly treatable, I recommend consulting a dermatologist to get a personalized regimen tailored to your specific skin and hair type.
