Pulling out hair by your root may damage your follicle temporarily, but a new bulb will eventually form, and new hair will grow again through that follicle. According to the TLC Foundation for Body-Focused Repetitive Behaviors, it may take a few months or more than a year in some cases.
“When done correctly, plucking removes the entire hair from the follicle, keeping it from growing back for up to 6 weeks. If you tweeze with skill in an area such as the eyebrows, it can give you more control than waxing,” Gonzalez says.
The constant pulling can cause strands of your hair to break or fall out. In time, the continuous pulling can damage your hair follicles. If you damage your hair follicles, your hair cannot grow back, so you develop permanent hair loss.
Another fairly common cause of permanent damage to hair follicles is through the excessive pulling or twisting of hair, which can lead to follicles closing prematurely and the gradual receding of the hairline. The excessive pulling or twisting of hair can lead to a form of hair loss known as traction alopecia.
DO NOT pluck large areas: Prolonged plucking and repetitive plucking can irritate and damage skin. Use tweezers on small areas of skin, like eyebrows and chin.
Electrolysis involves the use of shortwave radio frequencies distributed through fine needles placed directly into your hair follicles. The intention is to destroy the hair follicle so that it doesn't stimulate new hair growth. This procedure needs to be done by a dermatologist or a certified electrologist.
However, repeated ripping of the hair from its follicle via waxing or plucking (which is essentially the same thing, when you think about it) will make hair grow back thicker, darker and coarser… and frequently, more plentiful and faster to re-grow.
If your hair follicles are damaged, you might notice one or all of these symptoms: Hair loss or hair thinning. Extreme dryness. Irritation, redness, or flakiness.
When hair follicles die, however, hair growth stops completely. To know if your hair follicles are still active, just take a look at the scalp on your head. If you see any hairs on your scalp—no matter how sparse, thin, short or fuzzy—your hair follicles are still alive and kicking and sprouting new hairs.
If hair is pulled out of the hair follicle, it can regrow. It's possible that a damaged follicle will stop producing hair.
Pros: Tweezing is useful for shaping eyebrows and removing stray hairs on the face and body. Cons: Besides being a slow and painful option, tweezing can break the hair instead of pulling it out, which can cause thicker regrowth. Also, there's a risk of infection if the tweezers are not properly sterilized.
This response is known as quorum sensing. The plucked, distressed follicles secreted CCL2, a chemical that generates a white blood cell response. This generated regrowth in the plucked hairs, plus stimulated new hairs to grow.
Regeneration of hairs after plucking is a population-based behavior that depends on the density and distribution of the plucked follicles. Plucking hairs from high density areas (middle and far right) led to significant hair regeneration 12 days later. Lower density plucking failed to induce follicle regeneration.
Hair follicles are mostly made of protein, and the lack of it promotes hair loss. Proteins 'feed' the hair from the inside. Foods high in protein, vitamins A, C, and E, minerals like zinc and iron, and omega-3 fatty acids can contribute to healthier hair.
It is possible to revive dead hair follicles in certain cases. You must take action if you are experiencing excessive hair loss or hair thinning instantly. If the hair follicles are at an initial stage of damage, the growth phase of hair can come back.
In most people, new hair eventually grows back in the affected areas, although this process can take months. Approximately 50 percent of people with mild alopecia areata recover within a year; however, most people will experience more than one episode during their lifetime.
Plucking can traumatize the hair follicle, and repeated trauma to any follicle can cause infection, scar formation or possibly lead to bald patches.”
Tweezing. It's a little time-consuming and can be painful, but tweezing your pubes is a low-risk way to get rid of stray curlies along the bikini line. According to Dr. White, this method plucks hair out at the root without irritating the skin (the way waxing or a depilatory can).
In biological terms, hair follicle looks like a tunnel-shaped structure situated in the epidermis (outer layer of the skin) . Hair growth starts at the bottom of the hair follicle. The root of your hair is made up of protein (keratin)  and derives its nutrition by blood from the blood vessels on the skin.
If you have extra or unwanted hair growth, electrolysis can provide permanent hair removal. It's safe to use for facial hair removal and on the rest of body. During your sessions, a trained electrologist removes the hair with an electric current. The procedure is not painful and has no long-lasting side effects.
