Precision Application for Your Personalised Hair Serum
 
At GrowBack, every hair treatment is personalised. Your serum is formulated using clinical assessment, scalp analysis and, in some cases, genetic insights to support the biological causes of your hair loss.
 
However, a powerful formula alone is not enough.
 
For topical hair treatments to work effectively, the active ingredients must reach the scalp and the follicular environment. When treatments are applied incorrectly, much of the product sits on the hair shaft instead of reaching the follicles.
 
This is why we recommend the Flo™ Brush to all clients using personalised serums.
 
The Flo™ Brush is a precision scalp applicator designed to deliver liquid treatments directly to the scalp with consistent distribution. Instead of coating the hair, it allows the serum to reach the follicle where hair growth begins.
 
When used correctly, it helps improve treatment accuracy, absorption and consistency.
 
A Tool Prescribed in Clinic
 
During consultations, one of the most common issues we see is incorrect application of topical treatments.
 
Many people apply their serum with a dropper or their fingertips. While this may appear convenient, it often results in uneven dosing and product being absorbed by the hair rather than the scalp.
 
For this reason, we treat the Flo™ Brush as part of the GrowBack application protocol.
 
In the same way that the right formulation matters, the right delivery method matters too. Using a precision applicator helps standardise treatment application so that the serum reaches the follicles consistently.
 
This allows the active ingredients in your personalised formula to work in the environment where hair growth occurs.
 
Why Application Matters
 
Hair follicles sit within the scalp and require direct exposure to topical treatments.
 
Hair fibres themselves can absorb liquid products very quickly. When treatments are applied using a dropper or hands, a large proportion of the serum can be lost before it reaches the follicular opening.
 
A precision applicator improves delivery by ensuring the serum is distributed directly across the scalp surface. This helps maintain accurate dosing and supports more consistent exposure of follicles to the active ingredients.
 
Correct delivery is therefore an important part of topical treatment success.

Key Benefits of the Flo™ Brush
Direct-to-Scalp Delivery
The bristles release serum when they contact the scalp, helping the treatment reach the follicles rather than coating the hair.
Even Coverage
Allows consistent distribution across thinning areas such as the temples, crown and vertex.
Reduced Product Waste
Ensures the serum is used efficiently rather than being absorbed by hair fibres.
Hygienic Application
Avoids unnecessary contact with hands and reduces contamination risk.
Optimised Absorption
The gentle brushing motion helps distribute the serum across the scalp surface while supporting circulation.
 
How to Use the Flo™ Brush
 
Step 1 – Fill the reservoir
Add your personalised GrowBack serum into the brush chamber.
Step 2 – Section the hair
Create small partings in the areas being treated.
Step 3 – Glide across the scalp
Move the brush slowly along the scalp so the bristles make contact with the skin.
Step 4 – Cover the treatment areas
Apply across the temples, crown or other areas of thinning as advised in your treatment plan.
Step 5 – Allow the serum to absorb

No rinsing is required.
A full application typically takes around five minutes per day.
 
Who Should Use the Flo™ Brush
 
This applicator is recommended for anyone using topical hair treatments, including:
• Clients using personalised GrowBack serums

• Clients undergoing scalp restoration protocols
 
It is suitable for all hair types and for both men and women.
 
Why We Recommend It to Every GrowBack Client
 
In clinical practice we frequently see inconsistent results due to incorrect application.
A precision applicator standardises how the treatment is delivered, helping ensure the serum reaches the scalp consistently each day.
This improves treatment compliance and allows the active ingredients to interact with the follicular environment as intended.
 
Think of the Flo™ Brush as the delivery system for your personalised serum.
 
Your formula provides the science.
The Flo™ Brush ensures it reaches the follicle.
