No. GRO+ Advanced Gel-Serum Pen has a lightweight, gel  texture that absorbs quickly, so it won’t leave your hair feeling greasy or weighed down.

GRO+ Advanced Hair Serum is designed for overall scalp coverage, helping boost visible fullness and density across the entire scalp. The GRO+ Advanced Gel-Serum Pen is made for precision application, so you can easily target specific areas where thinning shows the most — like the temples, hairline, part or a defined patch of thinning.

Yes! In fact, they’re designed to complement each other. Use the GRO+ Advanced Hair Serum for all-over scalp coverage, then follow with the GRO+ Advanced Gel-Serum Pen to target areas with more noticeable thinning — like the temples, hairline or part — for extra focused support.

For safe, effective results, clean the applicator with 70% isopropyl alcohol after each use. If buildup is minimal, cleaning once a week is sufficient.

Twist the pen to ON, then place the applicator directly on your scalp. Click once to dispense the product, then massage it in. Repeat on any other areas of concern. Do not rinse. Use daily.

Each GRO+ Advanced Gel-Serum Pen contains approximately 150 clicks (applications). 1 click = 1 targeted application.

How long it lasts depends on how many targeted spots you apply it to each day:

• 1 click per day: lasts about 5 months
• 2 clicks per day: lasts about 2.5 months 
• 3 clicks per day: lasts about 1.5–2 months
