What id do is keep the pictures now.
In a couple weeks/months, take new pictures and compare. If their is no noticeable change; hairloss is not aggressive.
For now id recommend you massage your scalp with a mask (oil)
Use a carrier oil, personally would recommend coconut oil.
Add castor oil and oil of your choice.
Peppermint oil, rosemary, argan oil and lavender have all been claimed to help stimulation and promote hair strength and growth.
Lightly heat them together using abit of each and massage onto scalp and leave on as long as possible then wash out.
Id recommend you use egg yolk that is full of biotin and protein which helps additionally.
Make sure you eat a wellbalanced diet full of protein for growth and repair. The main things id recommend is food that are high in vitamin bs (specifically biotin) and omega 3s and omega 6s - these are found in foods such as eggs, oily fishes and seeds. Supplements can be consumed to help this. Drink plenty of water (or drinks like green tea) to hydrate you making cells hydrated will help increase the growth and health of the cell. Excercise.
Living a stress free life and environememt will also be good, do hobbies, meditate and so Forth. A rumour is that excessive masturbation can accelerate hair loss as ejaculating increases DHT. Not its debatable but might be worth limiting it.
DHT is the hormone most responsible to the causes of hairloss which is converted from testosterone.
Now you can use saw palmetto or pumpkin seed oil whixh is believed to mimic (in such a mild form) of finnasteride (propecia) which helps reducing dht levels,. This might not be so effective.
Speaking of that you can try topical produxts such as caffeine (caffeine shampoo) and minoxidil (Rogain) which help stimilate the roots. This is best used on thinning hair and rarely grows the hair back. This doesnt help too muxh on the temples so i wouldnt particularly reccomend minoxidl, buf i would for caffeine.
Finnasteride is a medicine that cuts and drops your dht levels. This usually promotes growth and stops recession for aslong as its taken. I wouldnt recommend this until you defianyly know your receeding bad as it has some side effects.
If your Caucasian (ehite european) your more than lilely will have a gene.
Good luck, ask if you need more info. Thanks.
