Better Because

  • Clinically studied: in a 44-day consumer perception study, 90% noticed new growth in as little as 6 weeks and 97% saw an overall improvement in their hair.*
  • In a 28-day study, 82% noticed increased thickness and 96% said they'd swap their current shampoo and conditioner for Biotin & Superfruit**
  • Redensyl™ helps re-energize the scalp to support visibly stronger, fuller-looking strands.
  • Rosemary, caffeine, and saw palmetto add botanical support for a balanced, healthier-feeling scalp.
  • Biotin and vegan collagen fortify strands with every wash, helping reduce the breakage that makes hair look thinner.
  • Elderberry and plum oil, rich in Vitamin E, add antioxidant protection and restore shine to stressed strands.
  • Drug-free serum, dermatologist tested, hypoallergenic. Harsh sulfate-free, silicone-free, paraben-free, color-safe, and vegan across the system.

*ProGRO Density+: 44-day third-party clinical study, 30 participants, April 2026. **Biotin & Superfruit: 28-day third-party clinical study, 33 participants, Aug. 2025.

Best For

For anyone facing scalp-level shedding and weaker, flatter-feeling strands, whether from stress, hormonal shifts, postpartum changes, GLP-1 or medication-related shedding, or the natural aging process. Formulated for a complete routine that helps address the root cause and reinforces strength through the lengths.

How to Use

  1. Apply ProGRO Density+ Serum daily to a dry or towel-dried scalp and massage for 60 seconds. No rinsing needed.
  2. When washing your hair, use shampoo with Biotin & Superfruit Volumizing Shampoo, then follow with the Conditioner.
  3. Use Oh My Growth Lengthening Vitamin Booster 3 times a week, applied to the scalp or mixed into conditioner.
    Pro tip: Apply the ProGRO serum before bed so it can work overnight.
