Hair is made of keratin that is pushed off the skin’s surface, and thus it is biologically considered to be part of the skin. The production of hair has three phases: the anagen phase, the catagen phase, and the telophen phase.
The anagen phase is where the actual growth happens. The rate at which the keratin is pushed off due to the rapid multiplication of the cells in the roots of the hair is accelerated. The typical accelerated rate is one centimeter per month, or 4 to 6 inches per year. The catagen phase is where hair stops growing and its follicles cut off blood supply and the cells that produce new hair. Club hair is formed in this phase. The telophen phase is where hair growth completely stops. At the end of this phase, hair gets shed off. One should not worry about that hair shedding, unless a great amount of hair is shed. When a great amount of hair is shed, is where hair thinning and hair loss happens.
Hair thickening products, or hair volumizing products, do exactly what they say on the package: they thicken hair by having its ingredients cling to the hair strands – leading to the appearance of fuller, thicker hair. They come in the form of shampoos, serums, sprays, and balms. Since hair thinning and hair loss are related – the former is commonly a cause of the latter – popular hair loss treatments such as minoxidil will certainly do the trick.
For those who want to go the natural and cheap route to hair thickening, the benevolent egg is a viable hair thickener. Keratin, after all, is a type of protein; and eggs are rich in protein. One can beat an egg or two, depending on the hair length, and apply it on wet hair before letting it sit for 5-10 minutes and washing it off.
People who are approaching old age have a greater tendency for their hair to become thinner, since the growth rate becomes slower and slower. Other factors for thinning hair include hormonal imbalance, certain medical conditions, certain medications, genetic inheritance from parents who also experienced hair loss, stress, skin burns, skin injuries, malnutrition, pollution, extreme weather conditions, and general improper hair care. An example of a medical condition that can aggravate hair thinning is alopecia areata, a condition where the immune system goes berserk and attacks unlucky hair follicles, creating a bald spot in areas where hair should normally propagate, like the head. Examples of medications that can trigger hair thinning are chemotherapy medications to combat cancer.
With the plethora of underlying causes of hair thinning in mind, it is very important that those causes must be addressed as soon as possible. Hair thickening products only give the appearance of thick hair and do not usually ameliorate the root causes of hair thinning. For best results, it is important that a three-hit combo of addressing the root cause of hair thinning, the usage of hair thickening products, and the usage of hair re-growing products must be employed.
