"I wish I had joined Club Roots as soon as I noticed hair loss. Not only did the shampoo imvprove the immediate appearance of my hair, but the combination of Minoxidil and Spark has kept my hair looking great in my 20s. Not to mention the peace of mind, knowing that there was a great company I trusted curating breakthrough hair growth products and I didn't have to think about it." -Matt

What Should I Fill in the HydroBrush?

Preserving your hair is all about finding the routine and treatments that work for you, as everyone is different. We created Spark with the mission of creating a comprehensive, multilateral approach to hair thinning. The development process began by sourcing ingredients of the highest purity >99%, tested each time for exact specifications before building the batch.

Each active ingredient is then encapsulated using patented NEOhair liposome technology. This advanced process allows topical ingredients to be highly effective and deliver to the active areas of hair follicle roots over a period of time, enhancing the effectiveness and dosing schedule.

But what about minoxidil 5%?

Yes, you can use minoxidil 5% in the HydroBrush. However, this treatment was not built for the HydroBrush and there are some issues you may have to manage from time to time. The high content of propylene glycol in minoxidil 5% can cause evaporation and clogging of the HydroBrush if the bristles are not rinsed after use and cover applied.

Why didn’t you combine minoxidil 5% with Spark?

While we sell a treatment like this in certain territories, current regulations in the United States do not allow for mixtures of ingredients with minoxidil.

Spark was designed with a special polymer to create a suspension when mixed with minoxidil 5%. By combining treatments in the HydroBrush, you can get the benefits of both minoxidil and the comprehensive treatment of Spark.

There are many users who have done this for months without the brush ever getting clogged. Since minoxidil 5% has high levels of propylene glycol even when mixed with Spark, be aware that if the lid is not properly applied after treatment you may have to unclog the brush with warm water before use.

  • Let the HydroBrush glideWhen the HydroBrush glides on your scalp, it will automatically dispense treatment easily.
  • Brush twice on top of head, once on either sideTo get complete scalp coverage, users should brush the top of their head twice, and once on either side. Since the crown is very sensitive to hair loss, sometimes it makes sense to brush an extra time on the crown.
  • Use Approved TreatmentsAll treatments offered by Roots Hair Club are built for the HydrobrushTM. Results may vary with other products.
  • Clean with Soap and WaterEvery month, you may wish to clean the brush. To clean the outside, wash with water and then wipe very gently with a paper towel. To clean the inside, pour soap water through the brush and then rinse with water.
  • Empty Before TravelNobody wants to get treatment over their clothes and suitcase. When travelling, simply dump out the treatment back into the TSA approved bottles you initially received. The rubber stopper included with the premium aluminum bottles allows for a leakproof flight.
