How Does Carthamus Tinctorius Extract In Shampoo Help Hair Grow?
Carthamus tinctorius, commonly known as safflower, has garnered attention in the hair care industry for its potential to promote hair growth. This plant extract is becoming increasingly popular as an ingredient in hair care products, including shampoos.
Carthamus tinctorius extract in solutions such as Luxe Cosmetics hair growth shampoo stimulates hair follicles and enhances blood circulation in the scalp, potentially leading to improved hair growth and thickness. Research has shown that this extract contains compounds that may inhibit 5α-reductase, an enzyme associated with hair loss. Additionally, it has been found to promote the expression of hair growth-related genes while suppressing those linked to hair loss.

Carthamus Tinctorius Extract and Its Role in Hair Growth
Carthamus tinctorius extract has shown promising effects on hair growth through multiple mechanisms. Research indicates it can stimulate hair follicles, inhibit factors that contribute to hair loss, and promote the expression of growth-related genes.
Understanding Carthamus Tinctorius L.
Carthamus tinctorius L., commonly known as safflower, is a plant with a long history of use in traditional medicine. Its florets contain bioactive compounds that have attracted scientific interest for their potential hair growth-promoting properties.
Safflower extract has demonstrated the ability to influence hair follicle function and cellular activity related to hair growth. Studies have examined both the ethanolic extract of C. tinctorius florets and specific components isolated from the plant.
Active Components and Their Effects on Hair Follicles
The ethanolic extract of Carthamus tinctorius contains several active components that affect hair growth. One key mechanism is the inhibition of 5α-reductase, an enzyme involved in converting testosterone to dihydrotestosterone (DHT).
DHT is implicated in androgenetic alopecia, so reducing its production may help prevent hair loss. The extract also stimulates the proliferation of dermal papilla cells and keratinocytes, which are crucial for hair follicle function and hair shaft formation.
Research has shown that C. tinctorius extract increases the expression of vascular endothelial growth factor (VEGF) and keratinocyte growth factor (KGF). These factors promote blood vessel formation and cell growth in hair follicles.
Benefits in Treating Alopecia and Promotion of Hair Growth
Studies on C. tinctorius extract have demonstrated its potential in treating various forms of alopecia and promoting hair growth. In animal studies, topical application of the extract or its components stimulated hair growth and increased hair density.
The extract's ability to inhibit 5α-reductase makes it particularly promising for androgenetic alopecia. Its effects on cell proliferation and growth factor expression suggest broader applications in hair loss prevention and treatment.
Researchers have also explored nanoformulations of C. tinctorius extract to enhance its efficacy. A nanostructured lipid carrier loaded with the extract showed superior hair growth-promoting effects compared to minoxidil in a mouse model.
Scientific Evidence and Practical Considerations
Carthamus tinctorius extract has shown promising results in hair growth promotion through various mechanisms. Research indicates its potential to stimulate key growth factors and inhibit hair loss-related proteins.
Synthesizing Research Findings: From Traditional Use to Clinical Studies
Studies on C57BL/6 mice demonstrated that Carthamus tinctorius floret extract (CTE) significantly stimulated hair growth. The extract promoted the proliferation of dermal papilla cells and keratinocytes, crucial components of hair follicles.
CTE increased the expression of vascular endothelial growth factor (VEGF) and keratinocyte growth factor (KGF), both important for hair growth. It also suppressed transforming growth factor-β1 (TGF-β1), a protein associated with hair loss.
Hydroxysafflor yellow A, a major component of safflower, showed potential as a hair growth-promoting agent. This compound exhibited antioxidant activity and influenced hair follicle stem cells.
Comparative Analysis with Common Hair Growth Treatments
CTE's effectiveness compares favorably with established treatments like minoxidil and finasteride. Unlike these synthetic drugs, CTE offers a natural alternative with potentially fewer side effects.
Minoxidil works by prolonging the anagen phase and increasing blood flow to hair follicles. CTE similarly promotes angiogenesis through VEGF stimulation.
5α-reductase inhibitors like finasteride block testosterone conversion to dihydrotestosterone. While CTE's mechanism differs, its suppression of TGF-β1 may provide comparable benefits in preventing hair loss.
Natural compounds like rosemary oil and pumpkin seed oil have shown promise in hair growth. CTE joins these alternatives as a potentially effective, plant-based option.
Safety, Side Effects, and Regulatory Status
CTE has demonstrated a favorable safety profile in studies. No significant toxic effects were reported in animal trials or cell culture experiments.
The FDA has not specifically approved CTE for hair growth treatment. It falls under the category of cosmetic ingredients, subject to less stringent regulations than drugs.
Potential side effects are mild and may include scalp irritation or allergic reactions in sensitive individuals. Long-term safety data is limited, warranting further research.
Users should be aware that results may vary. Factors like genetics, lifestyle, and chemical exposure can influence hair growth outcomes. Consultation with a healthcare professional is advisable before starting any new hair treatment regimen.
Conclusion
Carthamus tinctorius extract shows promise as a natural ingredient for promoting hair growth in shampoos. Its active compounds appear to inhibit 5α-reductase and stimulate dermal papilla cells, potentially countering hair loss and encouraging new growth. While more research is needed, preliminary studies indicate this safflower-derived extract may offer a safe, plant-based option for those seeking to improve hair health and fullness.
