Im 8 months into my high top (drop fade) locs and I felt your pain on coming to terms with your undercut situation I wish I had a full set or very low tapers to start but it is what it is .. gotta stay dredicated lol
I think when you did the first retwist you set yourself up for thinning of locs. Because free forming your hair gets stronger as it grows and combine the afro type foundation you have when free forming I think looks the strongest and is the strongest it's a total and complete crown of locs growing onto one helmet of hair but when you stopped and got that retwist that I believe is when you weakened your locs foundation because now it's nolonger a crown of locs but separate twisted locs and that is when it's a weaker foundation because they are separated
if you ask me in think every 3 months you should retwist because I used to do it every month and sometimes every 2 months but after i cut my hair bald I realized my hair don't grow long enough to retwist every 2 months even tho my hair got really frizzy it look like "new growth " but it's not especially if your parts is skinny wait 3 months an if you don't there gunna break and turn really skinny one more thing KEEP YOUR HEAD COVERED when you have starter locks because lint WILL find its way in your hair
When you started wit the sponge did you twist with your fingers also how did you maintain after u wake up, also how much pressure on the sponge because I’m trying to start my freefroms
