Statistically, hair is one of the first things, after teeth, that we look at in new people we meet, No wonder everyone wants them to be as numerous as possible and to make a good impression. So what should we do if we notice the beginnings of excessive hair loss? Can CBD oil help with this problem? How does CBD oil help with baldness?
When can we speak of excessive hair loss?
Our hair falls out every day, with every combing, and this is a completely normal physiological process. We lose about 70-100 hairs a day, although this is definitely an individual matter and can vary in either direction and is influenced by many factors, such as vitamin deficiencies, medication, age, inflammation of the body or chemical treatments such as bleaching or colouring the hair. However, losing more than 100 hairs a day and lasting more than a few weeks becomes problematic. Such excessive hair loss may be a precursor of alopecia due to an imbalance between hair loss and hair regrowth. If you do not want the problem to grow at this stage, it is worth taking action against hair loss.
Firstly, it is useful to familiarise yourself with the growth phase of the hair in order to have an idea of what transformations are taking place on the scalp.
The hair growth cycle is divided into 3 phases:
- The anagen phase - anagen, or hair growth phase, which lasts 2-7 years,
- The catagen phase - catagen, the so-called transitional phase, lasts about 2-3 weeks,
- Telogen phase - telogen, or the phase of resting and falling hair, lasts approximately 2-4 months.
Hair on the head is always in different phases, so there is never a period during the year when the scalp is devoid of any hair. The anagen (growth) phase in women is usually slightly longer than in men. On average, uncut hair is 30-40 cm long. The transition phase (catagen) is short and hair stops growing during this phase. This is followed by a hair resting phase (2-4 months), after which the hair falls out with the root.
Types of alopecia
The most common types of alopecia:
- androgenetic alopecia- is the characteristic loss of hair on the temples and top of the head. It is most common in men, much less common in women, due to higher levels of male hormones or medication. The hair then becomes thin and sparse, which is an aesthetic problem for both sexes.
- alopecia areata- is classified as a chronic autoimmune disease in which the hair follicles are damaged and the hair falls out in such a way that extensive patchy-like patches form on the scalp. The disease mainly affects children, and two-thirds of sufferers are under 30 years of age.
- telegon alopecia- mainly affects women, occurs when most of the hair is in the telogen phase, while the amount of hair remaining in the two initial growth stages decreases. Hair loss and destruction, occurs in this type of alopecia much more frequently than the process of new hair growth. This results in the appearance of visible thinning of the hair on the scalp.
Although there is currently little research focusing on the effects of CBD oils when it comes to hair loss, one of the most recent known studies took place in 2021, which aimed to observe the effects of high-concentration CBD when applied topically-directly to the scalp. It was investigated how CBD oil would react with hair loss or severe thinning of the hair, which is also a direct cause of androgenetic alopecia. During the interaction of the cannabinoid with the corresponding receptors of the endocannabinoid system, which are found in the hair follicles (these are the ones that control the phases of the hair cycle), a clear extension of the shaft of the newly formed hair was noticed. The study also showed that the use of lower concentrations contributed to significant hair growth. It was also found that CBD has already been qualified as a substance that could be used as a replacement for pharmacology or as a complementary treatment in androgenetic alopecia, thanks to its therapeutic and hair growth-stimulating properties. The results are indeed promising.
CBD oil can also be treated as a shampoo additive - initially, start by using such an enrichment once a week. Then use it more and more often and observe the effects and modify the dosage. At the same time, remember to cleanse your scalp thoroughly, which lays the foundation for the formation of new hair.
Similar conclusions have been drawn from other studies, also published in 2021. Preclinical evidence suggests that topical application of CBD oils may be effective for some skin conditions and inflammatory diseases, although the elucidation of the underlying molecular mechanisms has not yet been fully identified and is still in the research phase.
CBD and hair loss
CBD is known for its interaction with the human endocannabinoid system (ECS). This system is involved in many physiological processes of the human body such as, among others, regulation of metabolism, endocrine metabolism, neurohormonal and neuroimmune connections, and thus assists the body in the pursuit of homeostasis, which is also essential for proper hair growth.
CBD has a decidedly complex mechanism of action, which translates into its extremely beneficial and broad biological properties. Numerous studies have proven, for example, its strong anti-inflammatory or antioxidant effects, which allow the aforementioned biological balance in the human body to be achieved and create better conditions for the formation of new hair follicles. It should be noted that CBD is a much stronger antioxidant than the popularly used vitamin C, and its anti-inflammatory effect is even several hundred times stronger compared to acetylsalicylic acid. Some studies on the use of CBD oils for alopecia are in the pre-clinical phase. It is worth keeping an eye on this issue, as the coming years are bound to bring new findings on the topic of alopecia and the use of CBD oils.
