Hair loss is multifactorial. Our comprehensive approach addresses all biological contributors to optimize your results.
Your genetic blueprint determines hair follicle sensitivity to hormones and predisposition to pattern hair loss. Androgenetic alopecia, the most common form of hair loss, is inherited through multiple genes from both parents. These genes affect the androgen receptor sensitivity in hair follicles, particularly in the frontal and crown regions of the scalp.
Hormonal imbalances, particularly involving dihydrotestosterone (DHT), can miniaturize hair follicles over time. DHT is created when the enzyme 5-alpha reductase converts testosterone. In genetically susceptible individuals, DHT binds to androgen receptors in hair follicles, causing them to shrink progressively with each growth cycle until they can no longer produce visible hair.
Essential vitamins, minerals, and proteins are the building blocks of healthy hair. Hair follicles are among the most metabolically active cells in the body, requiring constant nutrient supply. Deficiencies in key nutrients can disrupt the hair growth cycle, leading to increased shedding, thinning, and poor hair quality. Nutritional optimization is a cornerstone of comprehensive hair restoration.
Chronic stress triggers telogen effluvium, a condition where significant numbers of hair follicles are pushed into the premature resting phase. This occurs through multiple pathways: elevated cortisol levels disrupt the hair cycle, stress-induced inflammation damages follicles, and neurogenic inflammation from stress hormones can directly impact scalp health. The effects typically manifest 3-6 months after the stressful event.
Transform your hair with regenerative treatments
The hair follicle is a complex mini-organ that cycles through phases of growth, regression, and rest. Understanding its structure is key to addressing hair loss effectively.
Dermal Papilla: The command center containing blood vessels and nerves that regulate hair growth
Matrix Cells: Rapidly dividing cells that form the hair shaft
Bulge Region: Contains hair follicle stem cells crucial for regeneration
Sebaceous Gland: Produces sebum to protect and moisturize hair
The dermal papilla is rich in growth factor receptors, making it highly responsive to regenerative treatments. Platelet-Rich Plasma (PRP) and Platelet-Rich Fibrin (PRF) deliver concentrated growth factors directly to the follicle, stimulating the dermal papilla and promoting stem cell activation in the bulge region.
Hair growth occurs in three distinct phases, each with unique characteristics and treatment implications. Understanding these phases is essential for optimizing regenerative therapy timing and expectations.
The active growth phase where hair follicles produce new hair cells at a rapid rate. During anagen, cells in the hair bulb divide quickly, pushing the hair shaft upward and outward. The length of the anagen phase determines maximum hair length and is genetically predetermined. This is the optimal phase for treatment intervention because follicles are metabolically active and responsive to growth factors.
Clinical Insight: Treatments like PRP and PRF are most effective during anagen, as growth factors can directly stimulate actively dividing cells in the hair matrix.
The transitional regression phase where hair growth slows and the follicle begins to shrink. The hair shaft detaches from the blood supply and the dermal papilla, forming a club hair. The outer root sheath shrinks and attaches to the root of the hair. This brief phase signals the end of active growth and prepares the follicle for the resting phase.
Clinical Insight: During catagen, follicles are less responsive to treatment as cellular activity decreases significantly.
The resting phase where the hair remains in the follicle but is no longer growing. The club hair is fully formed and anchored in place while a new hair begins forming beneath it in the follicle. At the end of telogen, the old hair sheds naturally (exogen) as the new anagen hair pushes it out. Approximately 50-100 hairs shed daily during normal telogen.
Clinical Insight: Stress, illness, or hormonal changes can push excessive follicles into telogen prematurely, causing telogen effluvium and noticeable shedding.
Our regenerative treatments work by extending the anagen phase and awakening dormant follicles. Growth factors in PRP, PRF, and exosomes stimulate stem cells in the follicle bulge, promoting the transition from telogen to anagen and increasing the duration of active growth. This results in thicker, healthier hair growth over multiple treatment cycles.
Optimal results typically require 3-6 treatment sessions spaced 4-6 weeks apart, with visible improvements appearing after 3-4 months as new anagen hairs mature.
Different types of hair loss require different treatment approaches. Understanding your specific condition is the first step toward effective treatment.
Affects 50% of men by age 50 and 40% of women by menopause
Pattern hair loss caused by genetic sensitivity to DHT (dihydrotestosterone), affecting both men and women.
How It Works:
DHT miniaturizes hair follicles, shortening the growth phase and eventually causing follicles to stop producing visible hair.
PRP and PRF contain growth factors that counteract DHT’s miniaturizing effects, promote follicle revascularization, and extend the anagen (growth) phase. Clinical studies show 30-40% improvement in hair density after 3-6 treatments.
Affects 2% of the population at some point in their lifetime
Autoimmune condition where the immune system attacks hair follicles, causing patchy hair loss.
How It Works:
T-cells mistakenly target hair follicle antigens, causing inflammation and forcing follicles into premature catagen (regression) phase.
Exosomes contain immunomodulatory factors that help regulate the immune response and reduce follicular inflammation. They also deliver regenerative signals that can reactivate dormant follicles. Emerging research shows promising results for autoimmune hair loss conditions.
One of the most common causes of diffuse hair loss
Temporary hair shedding triggered by stress, illness, surgery, or hormonal changes that push follicles into the resting phase prematurely.
How It Works:
Physical or emotional stressors disrupt the normal hair cycle, causing up to 70% of follicles to enter telogen (resting phase) simultaneously, leading to excessive shedding 2-3 months later.
A targeted supplementation plan replenishes key nutrients (iron, zinc, vitamin D, B-vitamins) that are often depleted after stress or illness. PRP helps accelerate follicle recovery and transition back into the growth phase. Together, they address nutritional gaps and support follicle stimulation.
Particularly common in individuals who frequently wear tight braids, ponytails, or hair extensions
Hair loss caused by prolonged tension on hair follicles from tight hairstyles, extensions, or chemical treatments.
How It Works:
Chronic mechanical stress damages the follicle structure and reduces blood flow to the dermal papilla, leading to follicle miniaturization and eventual scarring.
PRF’s fibrin matrix provides sustained release of growth factors over 5-7 days, promoting tissue repair and follicle regeneration. Early intervention is crucial before scarring occurs. Combined with proper hair care products, PRF can restore damaged follicles.
Your scalp is a complex ecosystem. The health of your scalp environment directly impacts hair follicle function and growth potential.
The scalp hosts billions of microorganisms—bacteria, fungi, and mites—that form a delicate ecosystem. When balanced, these microbes protect against pathogens and maintain scalp health. When disrupted, they can trigger inflammation and hair loss.
To support a healthy scalp microbiome, choose a pH-balanced leave-in like Folliq Lab’s Stem Cell Growth Elixir—lightweight and non-occlusive, it respects the scalp’s 4.5–5.5 pH and delivers growth-supportive botanicals for calmer, healthier follicles on its own or alongside PRP/PRF.
Chronic scalp inflammation—from microbiome imbalance, pollution, or autoimmune responses—creates a hostile environment for hair growth. Inflammatory cytokines signal follicles to enter the catagen (regression) phase prematurely.
→IL-1β and TNF-α cytokines inhibit hair shaft production
→Oxidative stress damages follicle stem cells
→Fibrosis can permanently damage follicle structure
Hair follicles are among the most metabolically active tissues in the body, requiring constant oxygen and nutrient delivery. Poor scalp circulation starves follicles and accelerates miniaturization.
→Dermal papilla requires rich vascular network
→Reduced blood flow decreases growth factor delivery
→Hypoxia triggers follicle regression pathways
PRP and PRF treatments address multiple scalp health factors simultaneously:
External factors and the natural aging process create cumulative damage to hair follicles over time. Understanding these mechanisms helps us develop targeted interventions.
Ultraviolet radiation penetrates the scalp, causing direct DNA damage to follicle cells and generating reactive oxygen species (ROS).
Airborne particulate matter and environmental toxins accumulate on the scalp, triggering oxidative stress and inflammation.
Harsh hair treatments, dyes, and styling products can damage both the hair shaft and the follicle itself.
Cellular Changes with Age
→Stem cell exhaustion: Follicle stem cells lose regenerative capacity, reducing hair density and growth rate
→Mitochondrial dysfunction: Decreased ATP production impairs the energy-intensive process of hair shaft formation
→Collagen degradation: Loss of dermal collagen weakens follicle anchoring and support structures
→Reduced growth factors: Age-related decline in IGF-1, VEGF, and other signaling molecules
