Hair loss in the bath

Is it normal to lose a lot of hair in the bath?

I believe that the little friends who clicked in must have and will have the same troubles, and every time they take a bath, they have to face the pain of “hair”. As the saying goes, my hair is everywhere, on the pillow, by the chair, on the bathroom floor, but not on my head. Is it normal to lose a lot of hair in the bath?

Hair loss in the bath

As the saying goes, my hair is everywhere, on the pillow, by the chair, on the bathroom floor, but not on my head.

In fact, the growth of hair is cyclical. In the beginning, there is a growth period of 2-6 years.

At this stage, the hair mother cells in the hair follicles continuously promote the production of hair roots and make the hair longer and longer. At this time, the hair is relatively stable and not easy to fall off.

After the growth period is over, there is a regression period of about 2-3 weeks. This is a transitional period, and the hair begins to “aging”.

After the degenerative period is a resting period of 2-3 months, at this stage the hair follicles stop growing, the hair roots begin to loosen, and are easily shed under external stimuli.

After the hair falls off, the hair follicle will enter the next cycle and grow new hair.

Under normal circumstances, hair in the growth phase should account for 90-95%, less than 1% in the anagen phase, and 5-10% in the resting phase. So it stands to reason that even for healthy hair, about 100 hairs fall out every day.

The shampoo that we deal with our hair every day, looking at its complex chemical composition table, I don’t know what is the use of its various ingredients. Why don’t you pick up your shampoo now and map out what it has in the end? The effect of it.


In the ingredient list, sodium Laureth sulfate (also known as sodium Laureth sulfate), Cocamidopropyl betaine, dimethiconol, dimethicone, Guar gum hydroxypropyl trimethyl ammonium chloride, cocamide MEA, etc. are all surfactants.

There are two types of silicon-containing active agents: dimethiconol and dimethicone.

These two substances are called silicone oils, which have the effect of being adsorbed on the surface of the hair to form a protective layer, which can make the hair shiny and smooth, and easy to comb. However, silicone oil should not be used in excess, otherwise, it will clog hair follicles and backfire.

Why is there so much surfactant in a bottle of shampoo? Because the function of a single active agent is limited, and excessive use can cause dry scalp and hair.

And if multiple active agents are combined, the dosage of each active agent can be reduced, and at the same time, a “combined attack” can be launched, which is more comprehensive in function and less harmful to the scalp and hair.


The function of the regulator is generally to adjust the pH and viscosity of the liquid so that the shampoo itself is weakly alkaline and has a moderate viscosity.

However, since the weakly alkaline environment will destroy the disulfide bonds connected to the keratin of the hair, we usually use acidic conditioners for care when washing the hair.

Other ingredients

The “others” here are actually included a lot, but because the added dose is not too much, they are simply grouped together.

Other ingredients also include pearlescent agents, moisturizers, flavors, preservatives, etc., which basically brighten hair color, keep hair from drying out, and increase fragrance as much as possible, extend shelf life, etc.

Special ingredients

The special ingredients here vary from shampoo to shampoo. If you want to increase the anti-dandruff effect, some shampoos will add piroctone ethanolamine salt. For shampoos that require advanced care, you may also add essences such as baking oil.

If it is a shampoo used by special people (such as babies), it will reduce the irritating ingredients as much as possible and add milder substances that can achieve similar effects.

Is it normal to lose a lot of hair during bathing?

This should be discussed separately because hair has a growth cycle and will fall off naturally, and shampoo contains a variety of chemical substances, which is irritating. So when the hair in the resting period encounters irritating shampoo, of course, there is only one ending-shedding. Therefore, a small amount of hair loss is normal when shampooing and flushing.

However, if the number of hair loss is large, you must be more vigilant, because this indicates that the proportion of hair follicles in the resting phase has begun to increase, and it is likely to continue to develop into hair follicles atrophy.

In this case, the hair follicles may not be able to start a new cycle from the resting phase to the growth phase.

It is worth mentioning that there is actually no perfect solution to the problem of hair loss. So don’t easily believe in the promotional effects of certain products. Regular work and rest and healthy life are the best ways to have beautiful hair!
