Not sure where to start? A 15-minute online pre-assessment is your first step. This short, focused session gives you the chance to speak directly with a trichologist, ask questions, and understand whether a full Hair & Scalp Assessment is right for you. It’s ideal if you’re unsure about your symptoms, new to clinical hair care, or simply want to understand what to expect.
Each consultation begins with a detailed assessment of your overall health, nutritional status, medical history, and lifestyle. This systems-based approach allows us to identify the underlying drivers of your hair or scalp concerns and design a personalised treatment plan that works from the inside out. For more complex or resistant cases, we may also suggest optional add-on tests such as genetic analysis or microbiome profiling for deeper clinical insight.
Exosome Therapy is an advanced regenerative treatment designed to stimulate hair follicles and support new, healthy hair growth — from the inside out.

FAQs
You can book an appointment up to 90 days in advance.
You do not have to do anything specific. It will be easier to carry out the consultation on clean hair, but a consultation can be carried out in most circumstances.
Exosome therapy is one of the most advanced regenerative treatments available for hair restoration. Backed by clinical research, it has shown impressive results in reactivating dormant hair follicles, improving scalp health, and promoting stronger, denser hair growth.
In clinical studies, exosome therapy has been shown to:
• Increase hair follicle cell activity by 177% within 48 hours
• Boost IGF-1 production — a key growth factor — by 115% in 24 hours
• Elevate miRNA-31 expression by 500%, helping to reinitiate the hair growth cycle
Results can vary depending on individual factors such as genetics, overall health, and the extent of hair loss. During your initial consultation, we assess your suitability and tailor the protocol to give you the best possible outcome.
Yes, Shannel works with all hair types and textures, offering personalised support for both men and women experiencing a wide range of hair and scalp concerns.
From early signs of shedding or thinning to more advanced and complex forms of hair loss, her approach is always tailored — combining scientific analysis with targeted, results-driven treatment plans.
Whether you’re looking to address temporary hair breakage, hormonal imbalances, or long-standing scalp conditions, Shannel provides expert care designed to meet your unique needs, no matter your hair type or stage of hair loss.
While everyone’s hair journey is unique, most clients begin to notice early improvements — such as reduced shedding, better scalp health, or new hair growth — within 12 weeks of starting their programme. However, true regeneration takes time.
We recommend following your personalised plan for approximately 12 months to achieve the most meaningful and long-lasting results. Hair growth is a gradual process, and consistency is key to restoring healthy function at the follicular level. Throughout your programme, we’ll monitor progress closely and make adjustments as needed to support your hair every step of the way.
Genetic testing offers a personalised approach to understanding hair loss by analysing specific variations in your DNA, known as single nucleotide polymorphisms (SNPs). These genetic markers can influence how your body responds to various factors related to hair growth, such as hormone sensitivity and nutrient metabolism.
For instance, SNPs in the Vitamin D Receptor (VDR) gene can affect the receptor’s function in hair follicle cells. Studies have shown that certain polymorphisms, like Taq-1 and Cdx-1, are more prevalent in individuals with Female Pattern Hair Loss (FPHL), suggesting a potential role in the condition’s persistence.
Similarly, variations in genes related to Dihydrotestosterone (DHT) receptors can influence androgen sensitivity, impacting hair follicle health and contributing to conditions like androgenetic alopecia.
By identifying these genetic factors, we can develop a targeted treatment plan that addresses the underlying causes of your hair loss, leading to more effective and personalised interventions.
We take a sample of your DNA with a cotton swab and get the results in 3-4 weeks. Once Shannel recieves your results, she can incorporate your own genetic profile into your treatment protocol.
Blood test data is an essential part of your hair and scalp assessment, as it helps us uncover underlying factors such as nutritional deficiencies, hormonal imbalances, or metabolic issues that may be contributing to your hair loss. However, you don’t need to have a blood test completed before your initial consultation.
If you have recent blood test results (within the last 12 months), you’re welcome to bring them to your appointment. If not, we can refer you to your GP, a private clinic, or the NHS to have them done either before or after your consultation. These results play a key role in creating your personalised treatment plan — and we’ll guide you through the process every step of the way.
