Do you know a hair loss remedy that actually works?

I love my hair. I have thick black hair (genetically). It started falling after I moved to Cochin for work. Split ends started appearing. Then I started taking better care of my hair. Here are the remedies I used to slow down my hair loss. The same methods worked for my brother too.

Hot oil massage using a mixture of coconut and castor oil once a week. Wash off with a mild shampoo after 30 minutes (I personally recommend Khadi shampoo).
Do not apply shampoo directly on your hair. Take half a glass of water, add required amount of shampoo, dilute it and apply on your hair.
Trim the ends of your hair once in three months.
Apply onion juice every week.
Do not wash your hair daily. Wash it every other day using only cold water.
Use Khadi shampoo instead of any other shampoo (You will see the results soon). I use Aloevera Hair Cleanser by Khadi. You can buy it online. It costs around Rs 150.
Never stretch or comb your wet hair. Use a cotton cloth to remove excess water. Do not blow dry.
No chemical treatment.
Apply natural aloe vera gel + egg white + banana mask every month. If natural aloe vera is not available, avoid it.
Take one spoon of flaxseed and boil it in one cup of water, when the mixture starts thickening, turn off the flame and keep it aside to cool. Take a cotton cloth and strain the flax seeds. Apply the gel on your hair after it cools down. Wash it off after 1 hour. This will give your hair a natural shine.
Eat protein rich foods like eggs, meat, sprouts, etc.
Always tie up your hair when you go out and braid it before going to bed.
Comb your hair twice a day.
Give your head a 5 minute massage before going to bed (this will improve blood circulation and hair growth at the same time).
Take a handful of tender guava leaves. Boil them in water. Keep them aside to cool. Use this water to wash your hair after showering. Do not rinse it off.
If well water is available (taken directly from a well, not from a water tank), use it to wash your hair. Never try this if the water is from a borehole or contaminated with chemicals.
