Is this a styling product or a scalp treatment?
It’s both. Stem Cell Thickening Foam™ delivers immediate styling benefits like root lift and volume, while 2% Apple Stem Cells help support the scalp’s natural hair growth cycle for thicker-looking hair over time. Think of it as styling powered by scalp care.
Can I use Stem Cell Thickening Foam™ with other Act+Acre scalp treatments?
Yes. Stem Cell Thickening Foam™ can be used alongside other Act+Acre scalp treatments like the Stem Cell Scalp Serum or Peptide Scalp Treatment. Apply your scalp treatment first and allow it to absorb, then apply the foam to damp hair before styling. The foam provides instant root lift and volume while continuing to support a healthy scalp environment over time.
Will this make my hair crunchy or stiff?
No. The formula is designed to provide lightweight, flexible hold without the stiffness or sticky feel often associated with traditional mousses. Hair remains soft, touchable, and naturally voluminous.
How much product should I use?
Start with 2–4 pumps for fine to medium hair, focusing on the roots and distributing through the hair. If your hair is longer or thicker, you can add more product gradually to build volume without weighing hair down.
