Comparison of hair growth methods: photobiomodulation vs other methods
There are many solutions to hair loss, each with its own strengths and limitations. Among them, photobiomodulation (PBM) is emerging as an innovative, non-invasive technology. How does it compare with other approaches, such as hair transplants, medication or topical treatments? This page explores the differences between these methods in depth, to help patients choose the solution best suited to their needs.
Photobiomodulation :
a gentle, natural approach
PBM uses light wavelengths to stimulate hair follicles and improve scalp health. It acts directly on the mitochondria of follicle cells, increasing ATP production to stimulate hair growth. Non-invasive and painless, PBM is suitable for a wide range of patients, including those who prefer to avoid surgery or medication.
Key features:
– Non-invasive
– No major side effects
– Overall improvement in hair health
– Suitable for regular, preventative use
Limitations :
– Results are progressive and depend on regularity
– Less effective in cases of advanced alopecia where follicles are irreversibly damaged
Hair transplants: an invasive solution for permanent results
Hair transplants involve the transfer of hair follicles from a donor area to a sparse area. These surgical procedures are often recommended for patients with advanced alopecia, when non-invasive treatments are not enough.
Key benefits:
Visible, permanent results
Suitable for severe alopecia
Limitations
High cost
Recovery period
Risk of side effects (infections, scarring)
Comparison with PBM :
PBM is non-invasive and can complement a hair transplant by improving healing and uptake of the grafted follicles.
Medication: chemical management of hair loss
Two drugs are commonly used to treat hair loss:
Finasteride: Reduces the impact of the hormones responsible for androgenetic alopecia.
Minoxidil: Directly stimulates follicle growth.
Product strengths :
Easy to use
Effective in slowing hair loss and stimulating regrowth
Limitations:
Potential side effects (reduced libido, skin irritations)
Continuous use required to maintain results
Comparison with PBM :
PBM has no systemic side effects and can be used in addition to medication to improve results.
Topical treatments: a targeted approach
Topical treatments include serums, shampoos and lotions enriched with nutrients, amino acids or plant extracts. They are often designed to nourish hair follicles and prevent external aggression.
Key benefits:
Easy to incorporate into a daily routine
Few or no side effects
Limitations:
Results limited to regular use
Less effective alone for advanced alopecia
Comparison with PBM :
PBM has a more in-depth effect on biological mechanisms. However, it can be complemented by topical treatments to maximise benefits.
Towards a combined strategy: the best of both worlds
For many patients, a combination of methods proves to be the most effective strategy. PBM can be used as a primary or complementary treatment:
Before a hair transplant: Prepare the scalp to optimise follicle uptake.
With medication: Reinforce their effects while reducing the doses required.
With topical treatments: Accelerate their absorption and benefits.
This personalised approach maximises the chances of success by adapting the treatment to individual needs.
Assessing the cost and accessibility of treatments
The choice of a hair growth method is often influenced by its cost and ease of access. Here is an analysis of the different treatments:
Photobiomodulation: Although the initial cost of the devices can be high, repeated sessions at home or in a clinic remain relatively affordable over the long term. What’s more, this method is widely accessible thanks to specialist clinics and approved personal devices.
Hair transplants: This surgical treatment represents a significant financial investment. Prices vary depending on the country, the surgeon and the number of grafts required, which limits its accessibility for some patients.
Medication: Solutions such as finasteride and minoxidil are affordable, but require ongoing purchase, which can lead to a significant cumulative cost.
Topical treatments: Relatively inexpensive, these products are readily available, but their efficacy is limited without rigorous and prolonged use.
This comparison shows that photobiomodulation offers an excellent compromise between cost, accessibility and effectiveness, especially when integrated into an overall hair care routine.
Conclusion
Photobiomodulation stands out for its simplicity, safety and positive impact on hair health. Although it may be less suitable for cases of very advanced alopecia, its integration into a combined strategy makes it an unavoidable option. Each method has unique benefits, but PBM offers a solid foundation for preventing hair loss, stimulating regrowth and maintaining healthy hair.
