Introducing a Problematic Chin to a good natured and sweet chin

I've had 2 Chins for about 2 months now. 1 het. ebony male and 1 std grey female. Both were paired in 3 days using the close quarter method. I've gotten a pink white female from a small pet shop who breed their own chins. I've tried introducing the male to the pink white female for about 2 weeks now. Below is a description of what I've done and the troubles I've encountered, hope to hear some advice from you guys.

Introduced the 2 chins (Het. ebony male and Pink white female) using the NZ method. Het. Ebony male approaches the Pink White female who bites and chases the Het. Ebony male. Bite marks on nose and toes and back.

After 3 days of no apparent improvement, used the close quarter method. I placed them both in a very tight dark box, no room to move. Pink White bit Het. Ebony male once on the first day of using the method. No biting observed on 3rd day of using this method.

Cleaned cage with Dettol Antiseptic solution (Strong smell to cover and remove all Chin smells) and placed both Chins inside. (By this time my std grey female had been relocated to my friend's house for temporary housing). Lots of fur biting and chasing by the pink white female. Het. Ebony male lost lots of fur on back and legs. I was told by a local Chin owner not to interfere unless blood was observed. No blood was observed so I did not stop the fight. Gave them dustbath together every day.

After a week of keeping both Chins in same cage and observing not much improvement, I've gave them both a wet bath together and used baby lotion on both of them. They now smell like babies. Cleaned their cage with dettol to remove smell and placed them in the cage. No fur-biting/chasing observed. However the Pink White female do get territorial during the following scenarios :

1) When I open the cage for them to come out during playtime. Only the Het. Ebony male will come out and run around the room while the Pink White will not budge but stay on the litter pan. When the Het. Ebony male returns into the cage, the Pink White female will chase the Het. Ebony male and bite his fur.

2) When the Het. Ebony male jumps down from the upper platform after spending some time in the upper decks to eat, the Pink White who is at the lowest platform on the Litter Pan or at the dark corner will chase and bite his fur. Most of the time they do get along.

Whenever the Pink White female shows signs of aggression, I've removed her from the cage and placed her in a small carrier. I carry the carrier up so that the Pink White female can observe me feeding the Het. Ebony male with treats or giving him toys.

Question 1 : What can I do to help them live together peacefully? Its been more than 2 weeks.
Question 2 : Will the fur grow back for my Het. Ebony Male? There are bald patches observed above the legs and on the back.

Any help or advice is greatly appreciated. Thanks.
