What is the difference between thinning hair, shedding, and alopecia areata?

Thinning hair involves the hair strands becoming progressively thinner over time, leading to less overall hair volume. Shedding refers to losing more hair than normal daily, which is often temporary. Alopecia areata is an autoimmune disease causing patchy hair loss on the scalp or body.

Thinning hair is a gradual process where the hair shaft becomes thinner, resulting in reduced hair density. It can be caused by aging, hormones, poor nutrition, medications, genetics, or other factors. With thinning hair, the number of hairs stays the same, but they become fine hair.

Shedding is when a person loses more hair per day than is typical, usually between 50-100 hairs. Excessive shedding may be temporary, caused by stress, illness, post-pregnancy, or other triggers. If the underlying trigger is addressed, shedding will often cease and density will return to normal.

Alopecia areata is an autoimmune disorder that causes patchy, smooth bald spots on the scalp or other hair-growing areas. It happens when the immune system attacks the hair strands, stopping hair production. It can occur in a small section or progress to complete hair loss. Alopecia areata is not caused by stress or usual hair shedding. It requires treatment to preserve the remaining hair.

How to prevent hair loss?

Seeing a board-certified dermatologist at the first signs of hair loss or thinning can help detect the causes early. This gives more options for effective treatment to keep the remaining hair healthy. Genetics, hormones, or health issues may be involved. Your dermatologist can then recommend drug-based hair serum for growth, natural 

Eating a nutritious diet with sufficient protein, iron, vitamins, and minerals promotes healthy hair growth. Incorporate leafy greens, fatty fish, eggs, beans, nuts, and healthy fats from oils or avocados. Stay hydrated as well.

Using topical minoxidil as directed can help maintain hair in the growth phase longer. It may be most effective for hereditary hair loss if started early.

Avoid styling practices that pull on and dry hair follicles like tight ponytails, harsh brushing, heat styling, and excessive washing. Use gentle shampoos and conditioners, let hair air dry when possible, and avoid rubbing wet hair with a towel.

Manage stress levels, as stress can influence hormonal balance related to hair growth. Get enough sleep, exercise, and consider stress-reduction techniques like meditation.

With early intervention, proactive lifestyle habits, and dermatologist guidance, the prognosis for maintaining healthy hair is good. Be gentle with hair and scalp health and address any underlying factors.

How does hair growth product work?

There are many ways a product can help regrow your hair.

Hair growth relies on the hair follicles - the specialized structure in the skin that grows a single hair. A hair growth serum or product aims to improve hair by targeting different parts of the hair cycle.

During the anagen phase, the hair follicle is active and grows new hair.

Minoxidil is a common ingredient that prolongs this phase, allowing more time for hair to grow longer before shedding. It widens blood vessels to improve nutrient and oxygen delivery to hair follicles.

Some products contain key ingredients like peptides, ginseng, and biotin that provide nutrients, antioxidants, and proteins to the follicles to encourage optimal growth. saw palmetto may help block DHT, a hormone linked to hair loss.

There is also melatonin hair serum, which, helps regulate the hair cycle and follicle metabolism to prolong the anagen growing phase during which new hair is produced.

Exfoliants remove dead skin cells and build up to ensure follicles remain open. Caffeine energizes follicles and can also lengthen the anagen-growing phase. Growth factor compounds stimulate cell signaling pathways to mimic natural processes.

Other products aim to clean and condition the scalp and existing hair strands to repair damaged hair and breakage. Gentle cleansers and conditioners with vitamins can improve elasticity and strength.

Lastly, laser devices and LED light therapy may act as a stimulating scalp treatment. However, more research is needed to confirm their efficacy.

As with anything, consistent use is key to seeing results from even the best hair growth serum.

How to choose the right hair growth serum for your hair type?

Here are some tips on choosing the best hair serum for hair growth based on your hair type:

For fine or hair fall, the best serum for hair growth and thickness typically has peptides, ginseng, or biotin to thicken strands without weighing hair down. Avoid oils or silicones that may leave fine hair limp.

If you have dry, brittle hair, choose serums with nourishing oils like argan, coconut, or marula to improve moisture levels and reduce breakage. Ensure the formula is lightweight enough not to look greasy.

For curly hair, serums with moisturizing ingredients like shea butter, aloe vera, or hyaluronic acid will enhance definition and cut down on frizz without being too heavy.

For oily roots or hair, choose a serum with green tea, tea tree oil, or apple cider vinegar to purify the scalp without stripping natural oils completely. Avoid thick, creamy formulas.

For color-treated hair, this hair type yearns for gentle formulas free of sulfates and alcohols, which can cause fading. Antioxidants like vitamin E and ferulic acid help lock in color.

For grey hair due to aging, look for serums that contain ingredients to nourish the scalp and follicles, such as peptides, amino acids, biotin, and antioxidant vitamins. Improving scalp health and circulation can help mitigate greying related to oxidative stress and aging.

Remember these for the optimal hair care routine:

  • Read reviews to ensure a serum works well for your specific hair texture - thin, thick, straight, wavy, etc. Results can vary.
  • Only use the recommended dosage a few times per week as directed. More is not better with potent serums.
