The terms melatonin and HLK in your Tugain Eva 5% Topical Solution are not the same; melatonin is a hormone known for regulating sleep and has some antioxidant properties that may benefit hair follicles, while HLK likely refers to a different ingredient or proprietary complex added to enhance the product's effect.

🩺 Understanding Your Query

Melatonin and HLK serve different roles in hair care formulations. Melatonin can help protect hair follicles from damage, whereas HLK is probably an additional component aimed at supporting hair health, but it is not melatonin itself.

🩺 What This Means for You

Using a product fortified with both means you are getting multiple active ingredients that may work together to improve hair growth and scalp health. They are complementary, not identical.

🩺 Next Steps

• Continue using the product as directed by your doctor.
• If you want detailed information about HLK, ask your prescribing doctor or pharmacist for the exact composition.
• Report any side effects or concerns to your doctor promptly.

Consult a dermatologist or trichologist for personalized advice on your hair treatment.
