Great set for thinning hair

After a few weeks, I started noticing small baby hairs around my hairline. My hair also looks fuller overall and feels much easier to manage.

Soft hair without feeling heavy

The shampoo and conditioner leave my hair soft and smooth without weighing it down. The serum absorbs quickly and does not leave a greasy finish.
