7. 1. 2026 Author: Petra Bečičková & development department

Hair loss is a natural part of the hair cycle. However, if your hair gets thinner more than usual, or if you notice weaker hair roots, it may be a signal that you need to adjust your scalp care, or your entire hair care routine.

Excessive Hair Loss: Causes, Solutions, and When Hair Serums Help

Excessive hair loss can be caused by hormonal changes, stress, seasons, as well as everyday hair care habits. This article summarizes the most frequent causes, practical steps for improvement, and the role of modern active serums, including Redensyl®.

1. How to Identify Excessive Hair Loss

Under normal circumstance, a person loses 50–100 hairs per day. If the loss is significantly higher, or if there is visible hair thinning in a particular area, it is considered excessive hair loss.

Signs You Should Pay Attention To:

  • More hair on your pillow or in the drain after washing
  • A considerable reduction in volume in length
  • Increased brittleness and weak roots
  • A more visible scalp in the hairline or on the top of the head

A considerable reduction in volume in length

Increased brittleness and weak roots

A more visible scalp in the hairline or on the top of the head


2. The Most Frequent Causes of Excessive Hair Loss

Hair loss can be temporary, long-term, or genetically determined. However, it is often a combination of several factors.

Hormonal Changes

Hormonal Changes

  • Pregnancy and the post-delivery period
  • Menopause
  • Discontinuation of contraceptives
  • Thyroid disorder

Stress and Mental Burden

Stress and Mental Burden

Long-lasting stress shortens the hair's growth phase of hair and can induce telogen effluvium, where a large amount of hair transfers into a resting phase at the same time.

Diet and Nutrition

Diet and Nutrition

  • Lack of sleep
  • Lack of minerals (especially iron, zinc, selenium)
  • Low protein intake
  • Smoking and alcohol

Seasons

Seasons

Our hair falls out more in spring and in autumn, this is a common seasonal phenomenon.

Inappropriate Washing and Styling Techniques

Inappropriate Washing and Styling Techniques

  • Too frequent washing
  • Hot air from the hairdryer
  • Strong tightening with hair bands
  • Aggressive chemical processes

3. What Really Helps: 7 Best Practices

Before selecting hair care products, it is ideal to try to identify the cause. Subsequent steps almost always lead to an improvement in hair condition.

1) Balanced Diet

Your hair needs structural substances, minerals and a healthy scalp. The most important are:

  • zinc, iron, selenium
  • vitamins A-E
  • biotin
  • omega-3 fatty acids
  • high-quality proteins

2) Gentle Washing and Scalp Care

  • Wash your hair gently with your fingertips.
  • Observe if your scalp is dry, tight or red.
  • Massage your scalp regularly.
  • If you dye your hair, choose gentle formulations free from ammonia or resorcinol.

3) Correctly Chosen Hair Care

Choose products with regenerating and strengthening ingredients, such as:

  • caffeine
  • hops and barley extracts
  • panthenol, creatine
  • beer for shine and volume

Avoid shampoos with aggressive surfactants that can excessively dry your hair and scalp.

4) Gentle Drying

  • Do not rub your hair with a towel.
  • Always dry your hair from the roots to prevent moisture retention at the scalp.
  • When drying your hair with a hairdryer, choose a medium temperature.

5) Suitable Hairbrush

  • Fine hair: soft brush with thicker bristles.
  • Thick hair: wooden brush or a comb with thin teeth.
  • Brush your hair from the ends towards the roots.

6) Use Hot Styling Moderately

Hot instruments weaken hair fibres. Reducing their use can bring visible improvement.

7) Minimization of Stress

Regular exercise, breathing exercises, relaxation or aromatherapy help.


4. The Role of Hair Serums and Active Substances

Hair serums act directly at the roots, where new hair is formed.

Due to concentrated active substances, they can:

  • promote the growth phase (anagen)
  • strengthen follicles
  • slow down premature transition to the resting phase (telogen)
  • improve the quality of newly growing hair

Why are serums more effective than shampoos in terms of promoting hair growth?

  • they act at the spots where hair growth starts
  • they are not rinsed out, so their effect lasts longer
  • they have a higher concentration of active substances
  • they can show the first results in 6–8 weeks

5. Key Ingredients of Modern Serums

Redensyl®

Unique natural complex from larch and green tea.

It activates the stem cells of hair follicles, promotes the growth of new hair, and helps reduce its excessive loss.

It is recommended mainly during hair thinning, seasonal loss or hormonal fluctuations.

Barley and Hops

6. How to Take Care of Particular Hair Types

Dry and Damaged Hair

It needs intensive hydration, nourishment and gentle conditioning substances.

Greasy and Fine Hair

Light formulas without heavy silicones, with minerals and soothing extracts, are suitable.

Hair with Dandruff or Sensitive Scalp

Seek gentle formulations and ingredients with a soothing and antimicrobial effect.

Dyed Hair

Colour protection requires antioxidant substances and proteins that prevent fading and promote shine.


7. Extra Care: Protection from UV and Pollution

Solar radiation and urban smog weaken hair follicles, increase brittleness, and can cause colour fading. What helps:

  • hydrating hair mists
  • protective sprays
  • extracts from apricot, wheat, barley and ginseng
  • polysaccharides and seaweed that promote hydration during heat treatment

Conclusion

Excessive hair loss can have many causes, however, most of them can be influenced by correct hair care, gentle habits and the use of active substances that promote growth and strengthen hair roots. 

When you focus on your scalp, a quality hair care routine, and long-term support with hair serums, you can achieve visible hair thickening and vitality, and improve the overall hair condition.


FAQ: The Most Frequent Questions About Hair Loss

How can I tell that my I am losing my hair excessively?

If you lose more than 100 hairs per day, or if you notice a decrease in volume, thinning in the hairline or a more visible scalp.

What is the most common cause of excessive hair loss?

Hormonal fluctuations, stress, lack of nutrients, seasons, inappropriate hair care habits or overuse of styling.

When does it make sense to start using hair serums?

When hair gets thinner, when it is weak, or when the transition to the resting phase is too quick. Serums target the hair roots directly, where hair starts to grow.

How long does it take for the serum to start working?

The first changes are visible in 6–8 weeks of regular use. A more significant result appears in three months.

What is Redensyl® and why is it used for hair loss?

Redensyl® activates the stem cells of hair follicles, promotes the growth of new hair, and helps reduce its excessive loss. It acts directly in the place where hair is formed.

Can stress cause significant hair loss?

Yes. Stress shortens the growth phase of hair, and it can induce telogen effluvium, meaning instant increased hair loss.

Is seasonal hair loss normal?

Yes, mainly in spring and in autumn. It is a natural phenomenon associated with the hair cycle.

Can a change in hair cosmetics help?

Yes, if the cause is scalp irritation, overuse of silicone products, lack of hydration, or inappropriate cleansing agents.

Can incorrect washing and styling cause hair loss?

Yes. Frequent washing, hot air, aggressive dyeing or tightening with a hair band can weaken roots and hair fibres.

When is it appropriate to seek an expert?

If hair loss lasts for more than three months, if it worsens quickly, if baldness appears, or if you suspect hormonal changes or a medical problem.
