What chemicals can damage hair follicles?
Chemical depilatories that contain sulfides, thioglycolates, or enzymatic depilatory agents destroy the projecting hair shafts, causing minimal damage to underlying skin.
If you damage your hair follicles after an injury, they can repair themselves and your hair will grow back. It could take up to four years before you see new hair growth out of damaged hair follicles, depending on the severity of your injury.
Causes of Cicatricial Alopecia
Generally, cicatricial alopecia is caused by inflammation, which damages the hair follicle. Damage can also stem from a trauma such as a burn or serious infection. The inflammation can involve different types of cells, including lymphocytes, natural killer cells, or several cell types.
DHT (Dihydrotestosterone) is a normal male hormone, or Androgen, that is produced from Testosterone by a very interesting group of enzymes, 5-alpha reductase 1, 2, and 3.
Hydrogen peroxide works to lighten hair by breaking down melanin in the hair shaft, and repeated use can weaken the hair, leading to extreme damage and breakage. Whilst this kind of styling damage can cause temporary hair loss, using peroxide continuously could also damage your hair follicle.
Dead hair follicles are most evident when the scalp's skin (where the hair once grew) becomes smoother and shinier in appearance. In other words, there'll quite literally be no hair there/no signs of regrowth if your hair follicles are completely dead.
There are a variety of methods available for the regrowth of hair follicles, from using medication to massaging your scalp to stimulate your hair directly. Currently, the most effective way to reactivate your hair follicles is by using medication, such as finasteride and minoxidil.
Unhealthy Diet - Having a diet lacking in essential nutrients such as protein, vitamins and minerals, especially iron and vitamin B12, can lead to gradual weakening of hair roots and hair loss is increasing day by day. Medications - Some medications can also weaken hair roots and cause premature hair loss.
Stress can push hair follicles into a “resting” phase so that they don't produce new hair strands. Over time, hair can fall out more easily, even if you're just washing, combing, or touching it. Telogen effluvium also can be caused by poor nutrition and changes in hormone levels.
New research has allowed scientists to generate new hair follicles — those tube-shaped pores that hug the strand and root of a hair — in vitro in a lab. It's a development that experts say can open pathways for better hair loss treatments in the future.
What is attacking my hair follicles?
Causes of Alopecia Areata
In alopecia areata, the immune system mistakenly attacks hair follicles, causing inflammation. Researchers do not fully understand what causes the immune attack on hair follicles, but they believe that both genetic and environmental (non-genetic) factors play a role.
Poisons that can cause hair loss include arsenic, thallium, mercury, and lithium.
The answer is hormones. DHT is a sex hormone that is a derivative of testosterone, but excess amounts of this hormone can affect the hair follicles. DHT interferes with the hair's growth cycle, shrinking and shortening the hair making it easier for it to fall out and more difficult for it to grow back.
Of the many nutrients and oils touted as natural DHT blockers, rosemary oil is one of the best proven. In a 2015 study, men applied either rosemary oil or minoxidil (an FDA-approved topical treatment for male pattern hair loss) to their scalps twice daily for six months.
Massage. Massaging the scalp, which people can combine with hair oils and masks, stimulates the scalp and may improve hair thickness . It's thought that stretching during the massage encourages hair growth and thickness in the dermal papilla cells, which are located in the bottom of the hair follicle.
But It May Cause Permanent Damage.
the bleach caused chemical burns and those burns can cause damage to your scalp and hair follicles. This can result in hair loss. hair was in bad condition prior to the bleaching service, it can also cause hair breakage at the scalp level.
Not only does bleaching raise the outer cuticle, it also damages the bonds inside the hair too (hair is made up of three types of bonds: hydrogen, disulfide and salt bonds) causing them to weaken and break, and when the internal structure of the hair is compromised, strands are more likely to split and snap.
SCALP BURNS
According to the NCBI, chemical burns can be caused by caustic chemicals, like hydrogen peroxide. The study states that a caustic reaction can result in irritant dermatitis, superficial chemical burns, and deep burns depending on how the ingredients are used and in what quantities.
"ACV unblocks follicles in the scalp so that strands have freedom to thrive," Ruggeri says. (Note: If you do use dry shampoo, Ruggeri advises spraying it on the mid-lengths of hair, rather than the roots, to prevent clogging the follicle).
When your hair follicles have died or become inactive the skin on the scalp takes on a smooth, shiny appearance. This indicates that hair loss has progressed to the stage of true baldness. Whether or not your follicles have died or not is harder to determine accurately by yourself than you might think.
Can closed hair follicles be reopened?
It depends. “If a follicle has closed, disappeared, scarred, or not generated a new hair in years, then a new hair wouldn't be able to grow,” Fusco says. But if the follicle is still intact, yes, it is possible to regrow the hair—or to improve the health of the existing thinner hairs.
It is recognized that for men it usually lasts 2-4 years, while for women 3-6 years. The catagen phase represents the moment in which the follicle starts to diminish and slowly ceases mitosis. It has a duration of around 7-21 days. It is difficult to find hair in a trichogram during the catagen phase.
A sitz bath can soothe clogged hair follicles in the groin and buttocks area. You can make one at home by mixing salt or sodium bicarbonate in the bath. Drugstores also have small plastic sitz baths that sit on your toilet seat.
Telogen effluvium hair loss — the type of hair loss linked to stress — typically affects your scalp and may appear as patchy hair loss. However, it can also cause you to shed more body hair or notice less hair on your body than you normally would.
The human body produces the hormone melatonin. This hormone has been confirmed by researchers to regulate the sleep cycle and increase hair growth. While sleep has a direct impact on the human body's natural hormones, it means that poor sleep reduces the amount of melatonin, potentially cause hair loss.
Prolonged periods of stress can result in telogen effluvium. Hair loss typically occurs about 3 months after the stressful event.
Electrolysis. This method sends an electrical current through a hair follicle, which will damage the follicle and prevent hair from growing. Because hair grows in cycles, it takes several sessions to get permanent hair removal. You'll also find kits that allow you to perform electrolysis at home.
"ACV unblocks follicles in the scalp so that strands have freedom to thrive," Ruggeri says. (Note: If you do use dry shampoo, Ruggeri advises spraying it on the mid-lengths of hair, rather than the roots, to prevent clogging the follicle).
Hydrogen peroxide can help get rid of some bacteria and fungi that cause folliculitis. Dilute the hydrogen peroxide with clean, sterile water or use it directly. Apply it onto your skin with a cotton swab. You can use a small spray bottle for larger areas.
Studies show that heat causes hair follicle damage. Chemicals, however, can destroy them and cause permanent damage. Reducing the usage of heating tools and chemicals will significantly reduce damage simply by not drying your hair at higher temperatures or using mild hair coloring ingredients.
How do you know if hair follicles are dead?
Dead hair follicles are most evident when the scalp's skin (where the hair once grew) becomes smoother and shinier in appearance. In other words, there'll quite literally be no hair there/no signs of regrowth if your hair follicles are completely dead.

Although it might be tempting to put coconut oil into your hair before bed and sleep on it, you should avoid this. Coconut oil hair masks can clog hair follicles, make your hair greasy, and reduce growth.
It also gets rid of the dirt and dust built on your scalp. In addition, citric juice in lemon restores the pH balance of the scalp. Applying lemon on hair aids in unclogging hair follicles.
There are many ways to repair damaged hair follicles naturally. Adding iron, B vitamins (particularly B6), omega-3 fatty acids, vitamin E, and zinc into your diet can help to repair damaged hair strands. Scalp massages with essential oils like peppermint or rosemary can keep hair follicles healthy.
As a natural clarifying agent, baking soda for hair works to clean strands by gently removing buildup and giving the overall head a detox.
Chronic folliculitis can be more difficult to treat. Antibiotics and other medications may not clear up chronic cases. If other treatment options fail, your doctor may recommend laser hair removal. During treatment, you should refrain from removing hair by plucking, waxing, or shaving.
Used for generations for skin ailments, witch hazel is safe and effective for a myriad of hair and skin conditions, including folliculitis. Witch hazel fights bacteria while soothing irritation, including itching and inflammation, according to a study published in the International Journal of Trichology.
Bacterial folliculitis treatment
Severe cases may require topical antibiotic treatment, for example, with mupirocin or clindamycin. Deep folliculitis (furuncles or carbuncles) may require treatment with oral antibiotics like dicloxacillin or cephalexin.
