You can do what ever you want!
Yes. More than enough. As long as you were thourough with applying the mayo - that's plenty of time.
twice a week
everyday when you shower right after you put shampoo in it
You should wash your hair every week if you have thick hair and you don't always put oils in your hair. UNLESS you have thin hair. You should wash your hair hair every other day!
Hair entensions should not have to be replaced, but every five to eight weeks you should go back to the salon they were put in at and have them re-weaved.
Honey, Peanut butter , eggs (raw) mayo, yogurt, etc. are all good choices.
If you have lice go to your local store and get real mayonnaise. You will put this in your hair. This will smother the lice bugs, nits, and eggs. Find a plastic bag or shower cap to put over your hair after you put on the mayo in your hair. My doctor said to keep this in for at least six hours. After six hours take a shower and scrub really hard to get the dead bugs, nits, and eggs out. This will also work with olive oil. But, I prefer mayonnaise.
Your own hair should not be damaged if your hair extensions are put in properly.
Honest to god i really don't think that you should put mayonaise in your hair, Unless you rhair is so dry that it will fall out then tou should put just a little but that's just me put what ever you want in your hair its your hair
As often as you want! there are no harsh chemicals that will damage your hair . Youre good to go.
In the winter you should grow your hair out and in the summer either put your hair up or cut your hair
