The normal human hair growth cycle consists of three phases: anagen, catagen, and telogen.The anagen phase, or active growth phase, lasts 2–5 years, and at least 85% of the hair follicles are in this phase at any one time.The catagen phase (transitional) lasts about 10–15 days, and only about 10% of the hair follicles are in this phase at any one time. The telogen phase (resting) lasts 100–150 days, and 10-15% of the hair follicles are in this phase at any one time

Why do you lose your hair?
 If you’re experiencing thinning hair, you’ve probably asked yourself why. Why are you losing your hair?Â
While it might not be a medical concern for you, there are typically four reasons for hair loss, each with its own treatment options: temporary hair loss (alopecia), age-related balding (androgenetic alopecia or AGA), chemotherapy or radiation therapy, and stress.Â
Temporary hair loss is usually caused by hormonal changes like those that accompany pregnancy or menopause; it should grow back once those hormones return to normal levels.Â
Age-related balding is caused by genetics and is permanent. Chemotherapy causes damage to your body’s cells, including those in your scalp; these cells can take months to recover after treatment ends.
 Stress can cause both temporary hair loss and permanently thinning hair over time if you don't address it quickly enough. Each type of hair loss has different treatments available; talk with your doctor about what's right for you.
How to regrow your lost hairÂ
While genetics is often what causes hair loss, there are a number of other reasons that may be responsible.Â
And while it’s difficult—if not impossible—to regrow lost hair, there are a number of steps you can take to help prevent further loss or promote healthy hair growth. With that in mind, here are some natural methods you can use to treat baldness.Â
A healthy diet is an essential part of maintaining healthy hair, so if you experience any kind of scalp issues, you should reevaluate your diet first. Be sure to include foods like fish and leafy greens in your daily meals, as both contain vitamins for hair loss. Consider supplements like vitamin C as well as biotin for faster results.Â

To speed up that process, apply natural treatments like onion juice or aloe vera gel directly onto your scalp twice a day for 10 minutes each time. Both of these ingredients have been shown to stimulate blood flow, which could aid in hair growth.Â
You could also try supplements like biotin or fish oil; while they won’t guarantee new hair growth, they could improve your overall health enough to allow you to grow back your locks on their own.
How does Rogaine work?Â
Rogaine is one of many FDA-approved treatments for male pattern baldness (androgenetic alopecia). In women, Rogaine can also be used to treat frontal fibrosing alopecia, a condition that causes irreversible hair loss on just the front half of your scalp.Â
Rogaine’s active ingredient, minoxidil, was originally developed as an oral medication to lower high blood pressure.Â
When it was discovered that it could promote hair growth when applied directly onto scalps in low doses, it became a popular over-the-counter topical solution for men and women who are experiencing thinning or receding hairlines.
There are various causes of hair loss, including genetics, medication, hormone imbalances, nutritional deficiencies, stress or shock trauma.
If you notice that your hair is falling out in patches or is starting to thin out at the crown or along your part line, then it might be time for a more thorough evaluation by a medical professional.Â
