At ModYu, we created the HT4 Scalp care system to take the uncertainty out of hair transplant recovery.

Too often, patients are left with products never designed for sensitive, healing scalps.

That’s why HT4 is different – it’s the first system scientifically formulated for scalp care before and after transplant.

About HT4

HT4 (P3) products have been rigorously tested by independent dermatologists. Clinical studies confirmed they are hypoallergenic, safe for sensitive skin, and in the case of the Comfort Night Serum proven not to clog pores or interfere with follicles.

That means you can feel confident using them on your healing scalp.
